The product of 2 consecutive odd integers is 483, what are these 2 odd integers? The answer are 21 and 23. How to find these 2 consecutive odd integers whose product is 483? 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 2 consecutive odd integers whose product is 483?

Method 1: Assumption Method

This is a common mathematical solution. Assuming that 2 * N + 1 is used to represent the first odd integer, so the second odd integer is 2 * N + 3.

Now, the product of 2 consecutive odd integers is 483, which can be expressed by equation

(2 * N + 1) * (2 * N + 3) = 483

Solving equations

(2 * N + 1) * (2 * N + 3) = 483

4 * N2 + 6 * N + 2 * N + 3 = 483

4 * N2 + 8 * N + 3 = 483

4 * N2 + 8 * N – 480 = 0

N2 + 2 * N – 120 = 0

(N – 10) * (N + 12) = 0

N = 10 or N = -12

So, 2 * N + 1 = 21 or -23

You can see that the first odd integer has 2 values 21 and -23. So, The second odd integer also has two values, 23 and -21.

Let’s verify whether the answer is correct?

The first set 21 and 23.

21 * 23 = 483. Correct.

Then let’s verify the second set of answers -23 and -21.

-23 * -21 = 483. This is also eligible.

So, there are two answers of 2 consecutive odd integers whose product is 483, one set is 21 and 23, the other set is -23 and -21.

The key to this method is to solve the quadratic equation. If you are not familiar with quadratic equations, the second or third method is recommended. 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, we need to find 2 consecutive odd integers whose product is 483, which can be regarded as the product of 2 identical numbers is 483. That is, find the 2nd root of 483. As long as we find this number, we can use this number as the fulcrum to find the consecutive odd integers that meet the conditions.

The equation is as follows

A2 = 483

With the help of the root calculator, you can easily calculate A = 21.977, round down to an odd integer A = 21.

The product of 2 consecutive odd integers is 483, one odd integer is 21, the other odd integer is 483 / 21 = 23.

21 and 23 are just two adjacent odd integers, which meet the requirements.

21 and 23 are positive integers. If their negative integers are taken, will their product be 483?

-23 * -21 = 483.

Yes, -23 and -21 are also the answer of 2 consecutive odd integers whose product is 483.

So, there are two answers of 2 consecutive odd integers whose product is 483, one set is 21 and 23, the other set is -23 and -21. The result is the same as the first method.

Obviously, this method needs to calculate the 2nd root first. If you can’t calculate the 2nd root manually, you need to use a root calculator to calculate it. 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 2 consecutive odd integers is 483, so these 2 consecutive odd integers are all divisors of 483. How to find these divisor numbers? First, decompose 483 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 2 consecutive odd integers whose product is 483.

  • The first step, decompose 483 by the smallest divisor except 1. 483 / 3 = 161;
  • The second step, 161 is decomposed by the smallest divisor except 1. 161 / 7 = 23;

By analogy, the following equation is obtained

483
= 3 * 161
= 3 * 7 * 23

Next, group the obtained divisors. Here, you need to divide the last row of numbers 3 * 7 * 23 into 2 groups. Obviously, one group is 23, the other group is 3 * 7 = 21.

So, 21 and 23 are the answer of 2 consecutive odd integers whose product is 483.

As with the second method, discuss the negative numbers to get another answer -23 and -21.

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
