Given numbers are 637,646,347,938

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

The LCM of 637,646,347,938 is 9567009998.

Find LCM of 637,646,347,938 with Prime Factorization

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

2 x 7 x 91 x 323 x 347 x 67 = 9567009998

Therefore, the lowest common multiple of 637,646,347,938 is 9567009998.

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 646 x 347 x 938 = 133938139972

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

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

347 : 1, 347

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,646,347,938, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

646:2x 17x 19

347:347

938:2x 7x 67

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 133938139972/(1x14)

LCM = 133938139972/14

LCM = 9567009998

Thus, we can understand that the LCM of 637,646,347,938 is 9567009998.
