Given numbers are 634,646,160,317

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

The LCM of 634,646,160,317 is 16382560.

Find LCM of 634,646,160,317 with Prime Factorization

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

2 x 317 x 1 x 323 x 80 x 1 = 16382560

Therefore, the lowest common multiple of 634,646,160,317 is 16382560.

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.

634 x 646 x 160 x 317 = 20773086080

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.

634 : 1, 2, 317, 634

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

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

317 : 1, 317

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,646,160,317, is 1.

Now, the common factors can be found like this.

634:2x 317

646:2x 17x 19

160:2x 2x 2x 2x 2x 5

317:317

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 317 = 1268

Therefore, the value for common factors is 1268.

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 = 20773086080/(1x1268)

LCM = 20773086080/1268

LCM = 16382560

Thus, we can understand that the LCM of 634,646,160,317 is 16382560.
