Given numbers are 637,939,920,906,810

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

The LCM of 637,939,920,906,810 is 2243538690120.

Find LCM of 637,939,920,906,810 with Prime Factorization

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

2 x 3 x 5 x 637 x 313 x 92 x 151 x 27 = 2243538690120

Therefore, the lowest common multiple of 637,939,920,906,810 is 2243538690120.

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.

637 x 939 x 920 x 906 x 810 = 403836964221600

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.

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

939 : 1, 3, 313, 939

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

906 : 1, 2, 3, 6, 151, 302, 453, 906

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,939,920,906,810, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

939:3x 313

920:2x 2x 2x 5x 23

906:2x 3x 151

810:2x 3x 3x 3x 3x 5

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

2x 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 403836964221600/(1x180)

LCM = 403836964221600/180

LCM = 2243538690120

Thus, we can understand that the LCM of 637,939,920,906,810 is 2243538690120.
