The product of 3 consecutive integers is 504, what are these 3 integers? The answer are 7, 8 and 9. How to find out these 3 consecutive integers whose product is 504? Here are three methods, especially the third method, which can be easily calculated without the help of other tools. Let’s introduce them one by one.

How to find 3 consecutive integers whose product is 504?

Method 1: Assumption Method

This is a common mathematical solution. Because these 3 numbers are consecutive integers, assuming that N is used to represent the first integer, then the second to fourth integers can be expressed as N + 1 and N + 2.

Now, the product of 3 consecutive integers is 504, which can be expressed by equation

N * (N + 1) * (N + 2) = 504

Solving equations

N * (N + 1) * (N + 2)  = 504

(N2 + N) * (N + 2) = 504

N3 + 2 * N2 + N2 + 2 * N = 504

N3 + 3 * N2 + 2 * N = 504

N3 + 3 * N2 + 2 * N – 504 = 0

(N – 7) * (N2 + 10 * N + 72) = 0

You can see that N contains a positive value 7.

Thus, when N = 7, the second integer is N + 1 = 8, the third integer is N + 2 = 9. So, the product of 3 consecutive integers is 504, these numbers are 7, 8, 9.

Let’s verify whether the answer is correct?

7 * 8 * 9 = 504. Correct.

Now, let’s verify if their negative value product is equal to 504.

-9 * -8 * -7 = -504. Invalid answer.

So, there is only one answer of 3 consecutive integers whose product is 504. The answer are 7, 8 and 9.

It can be seen from the above calculation process that the solution process is not simple. Therefore, this method is only suitable for finding the product of 2 or 3 consecutive integers. If there are more than 2 consecutive integers, it is recommended to use the second or third method. Now we will introduce the second method.

Method 2: Root Sign Method

According to the definition of the root sign, if An = B, then A is the nth root of B to the nth power. An is the multiplication of n identical A. Now, there are many tools that can directly calculate the value of the nth root.

Therefore, we need to find 3 consecutive integers whose product is 504, which can be regarded as the product of 3 identical numbers is 504. That is, find the 3th root of 504. As long as we find the same number, we can use this number as the fulcrum to find the consecutive integers that meet the conditions.

The equation is as follows

A3 = 504

With the help of the root calculator, you can easily calculate A = 7.958, round down to an integer A = 7.

7 is one of 3 consecutive integers. The position of 7 will be the key to finding the answer.

  • If 7 is the first integer, these 3 consecutive integers are 7, 8, 9, their product is 7 * 8 * 9 = 504.
  • If 7 is the second integer, these 3 consecutive integers are 6, 7, 8, their product is 6 * 7 * 8 = 336.
  • If 7 is the third integer, these 3 consecutive integers are 5, 6, 7, their product is 5 * 6 * 7 = 210.

Through the above analysis, it can be seen that the first group satisfies the condition whose product is 504. That is, 7 is the first integer, and these 3 consecutive integers are 7, 8 and 9.

Similar to the first method, considering whether their negative number form can be satisfied, it is ignored here.

Obviously, this method requires the help of the root calculator to smoothly conduct group discussions. What if there is no such auxiliary tool? It doesn’t matter, let’s move on to the third method.

Method 3: Divisor Method

First of all, we must understand what is divisor. The divisor is also called a factor. If A is divisible by B, B is called A divisor.

Obviously, the product of 3 consecutive integers is 504, so these 3 consecutive integers are all divisors of 504. How to find out these divisor numbers? First, decompose 504 with the smallest divisor more than 1, and then decompose the obtained quotient until the quotient can no longer be decomposed. Note that the indecomposable here means that no other divisor can be found except 1 and itself. This means that the final quotient is a prime number.

Back to the question: find 3 consecutive integers whose product is 504.

  • The first step, decompose 504 by the smallest divisor except 1. 504 / 2 = 252;
  • The second step, 252 is decomposed by the smallest divisor except 1. 252 / 2 = 126;
  • The third step, 126 is decomposed by the smallest divisor except 1. 126 / 2 = 63;

By analogy, the following equation is obtained

504
= 2 * 252
= 2 * 2 * 126
= 2 * 2 * 2 * 63
= 2 * 2 * 2 * 3 * 21
= 2 * 2 * 2 * 3 * 3 * 7

Next, group the obtained divisors. Here, you need to divide the last row of numbers 2 * 2 * 2 * 3 * 3 * 7 into 3 groups. Obviously, 7 should be a single group. If 7 is multiplied by any other number, 3 consecutive integers cannot be found. So, 7 should be one of the 3 consecutive integers we are looking for.

The next step is easy. Discuss the position of 7 , just like the second method. You can find 3 groups of consecutive integers

  • 7, 8, 9
  • 6, 7, 8
  • 5, 6, 7

Multiplying each group of consecutive integers, we can easily find the answer are 7, 8 and 9.

Of course, we must also consider, if the answer integers are all negative numbers, is their product equal to 504? See the first method for details.

Is not it simple? The whole process does not require any tools at all. Of course, if you have any questions about the grouping process, please refer to another article Consecutive Integers Calculator Based On A Given Product
