Given numbers are 637,388,504,920

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

The LCM of 637,388,504,920 is 511612920.

Find LCM of 637,388,504,920 with Prime Factorization

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

2 x 2 x 2 x 7 x 91 x 97 x 9 x 115 = 511612920

Therefore, the lowest common multiple of 637,388,504,920 is 511612920.

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 388 x 504 x 920 = 114601294080

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

388 : 1, 2, 4, 97, 194, 388

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

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 637,388,504,920, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

388:2x 2x 97

504:2x 2x 2x 3x 3x 7

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 2x 2x 2x 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 114601294080/(1x224)

LCM = 114601294080/224

LCM = 511612920

Thus, we can understand that the LCM of 637,388,504,920 is 511612920.
