Add up these 100 numbers

5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50 + 55 + 60 + 65 + 70 + 75 + 80 + 85 + 90 + 95 + 100 + 105 + 110 + 115 + 120 + 125 + 130 + 135 + 140 + 145 + 150 + 155 + 160 + 165 + 170 + 175 + 180 + 185 + 190 + 195 + 200 + 205 + 210 + 215 + 220 + 225 + 230 + 235 + 240 + 245 + 250 + 255 + 260 + 265 + 270 + 275 + 280 + 285 + 290 + 295 + 300 + 305 + 310 + 315 + 320 + 325 + 330 + 335 + 340 + 345 + 350 + 355 + 360 + 365 + 370 + 375 + 380 + 385 + 390 + 395 + 400 + 405 + 410 + 415 + 420 + 425 + 430 + 435 + 440 + 445 + 450 + 455 + 460 + 465 + 470 + 475 + 480 + 485 + 490 + 495 + 500 = 25250

It can be seen that the sum of first 100 multiples of 5 is 25250, which is consistent with the result calculated by the first method.

3. Common divisor method

Since these 100 numbers are all multiples of 5, 5 is the common divisor of these 100 numbers. We can first extract the common divisor 5, and then calculate the sum of these 100 numbers which are divided by the common divisor 5. Finally, multiply the sum by 5 to get the sum of first 100 multiples of 5.

Because these numbers are first 100 multiples of 5, after extracting the common divisor 5, these 100 numbers are 1 to 100. Now, calculate the sum of 1 to 100.

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 + 21 + 22 + 23 + 24 + 25 + 26 + 27 + 28 + 29 + 30 + 31 + 32 + 33 + 34 + 35 + 36 + 37 + 38 + 39 + 40 + 41 + 42 + 43 + 44 + 45 + 46 + 47 + 48 + 49 + 50 + 51 + 52 + 53 + 54 + 55 + 56 + 57 + 58 + 59 + 60 + 61 + 62 + 63 + 64 + 65 + 66 + 67 + 68 + 69 + 70 + 71 + 72 + 73 + 74 + 75 + 76 + 77 + 78 + 79 + 80 + 81 + 82 + 83 + 84 + 85 + 86 + 87 + 88 + 89 + 90 + 91 + 92 + 93 + 94 + 95 + 96 + 97 + 98 + 99 + 100 = 5050

Next, multiply the sum by 5

5050 * 5 = 25250

The answer came out. The sum of first 100 multiples of 5 is 25250, which is consistent with the first and second methods.

Alright, the three methods are introduced. Please leave a message to tell me which method is more suitable for you?
