Given numbers are 128,956,364,637

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

The LCM of 128,956,364,637 is 19487104.

Find LCM of 128,956,364,637 with Prime Factorization

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

2 x 2 x 7 x 13 x 32 x 239 x 1 x 7 = 19487104

Therefore, the lowest common multiple of 128,956,364,637 is 19487104.

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 956 x 364 x 637 = 28373223424

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

956 : 1, 2, 4, 239, 478, 956

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

637 : 1, 7, 13, 49, 91, 637

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,956,364,637, is 1.

Now, the common factors can be found like this.

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

956:2x 2x 239

364:2x 2x 7x 13

637:7x 7x 13

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 7x 13 = 1456

Therefore, the value for common factors is 1456.

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 = 28373223424/(1x1456)

LCM = 28373223424/1456

LCM = 19487104

Thus, we can understand that the LCM of 128,956,364,637 is 19487104.
