Calculate the LCM of 125,375,646,355

Given numbers are 125,375,646,355

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 125,375,646,355 is 17199750.

Find LCM of 125,375,646,355 with Prime Factorization


5 125, 375, 646, 355
5 25, 75, 646, 71
5 5, 15, 646, 71
1, 3, 646, 71

Multiply the prime numbers at the bottom and the left side.

5 x 5 x 5 x 1 x 3 x 646 x 71 = 17199750

Therefore, the lowest common multiple of 125,375,646,355 is 17199750.

LCM Formula to Find Lowest Common Multiple of 125,375,646,355

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

125 x 375 x 646 x 355 = 10749843750

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

125 : 1, 5, 25, 125

375 : 1, 3, 5, 15, 25, 75, 125, 375

646 : 1, 2, 17, 19, 34, 38, 323, 646

355 : 1, 5, 71, 355

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,375,646,355, is 1.

Now, the common factors can be found like this.

125:5x 5x 5

375:3x 5x 5x 5

646:2x 17x 19

355:5x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 5x 5x 5 = 625

Therefore, the value for common factors is 625.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 10749843750/(1x625)

LCM = 10749843750/625

LCM = 17199750

Thus, we can understand that the LCM of 125,375,646,355 is 17199750.
