Given numbers are 637,354,635,220

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

The LCM of 637,354,635,220 is 3150207060.

Find LCM of 637,354,635,220 with Prime Factorization

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

2 x 5 x 637 x 177 x 127 x 22 = 3150207060

Therefore, the lowest common multiple of 637,354,635,220 is 3150207060.

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 354 x 635 x 220 = 31502070600

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

354 : 1, 2, 3, 6, 59, 118, 177, 354

635 : 1, 5, 127, 635

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,354,635,220, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

354:2x 3x 59

635:5x 127

220:2x 2x 5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 31502070600/(1x10)

LCM = 31502070600/10

LCM = 3150207060

Thus, we can understand that the LCM of 637,354,635,220 is 3150207060.
