Calculate the LCM of 942,637,715,920

Given numbers are 942,637,715,920

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

The LCM of 942,637,715,920 is 3036273240.

Find LCM of 942,637,715,920 with Prime Factorization


2 942, 637, 715, 920
5 471, 637, 715, 460
13 471, 637, 143, 92
471, 49, 11, 92

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

2 x 5 x 13 x 471 x 49 x 11 x 92 = 3036273240

Therefore, the lowest common multiple of 942,637,715,920 is 3036273240.

LCM Formula to Find Lowest Common Multiple of 942,637,715,920

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.

942 x 637 x 715 x 920 = 394715521200

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.

942 : 1, 2, 3, 6, 157, 314, 471, 942

637 : 1, 7, 13, 49, 91, 637

715 : 1, 5, 11, 13, 55, 65, 143, 715

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,637,715,920, is 1.

Now, the common factors can be found like this.

942:2x 3x 157

637:7x 7x 13

715:5x 11x 13

920:2x 2x 2x 5x 23

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

2x 5x 13 = 130

Therefore, the value for common factors is 130.

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 = 394715521200/(1x130)

LCM = 394715521200/130

LCM = 3036273240

Thus, we can understand that the LCM of 942,637,715,920 is 3036273240.
