Given numbers are 128,726,671,557

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

The LCM of 128,726,671,557 is 1578707328.

Find LCM of 128,726,671,557 with Prime Factorization

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

2 x 11 x 64 x 33 x 61 x 557 = 1578707328

Therefore, the lowest common multiple of 128,726,671,557 is 1578707328.

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.

128 x 726 x 671 x 557 = 34731561216

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

671 : 1, 11, 61, 671

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,726,671,557, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

726:2x 3x 11x 11

671:11x 61

557:557

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 34731561216/(1x22)

LCM = 34731561216/22

LCM = 1578707328

Thus, we can understand that the LCM of 128,726,671,557 is 1578707328.
