Given numbers are 128,728,672,979,657

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

The LCM of 128,728,672,979,657 is 7492028544.

Find LCM of 128,728,672,979,657 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 3 x 7 x 4 x 13 x 1 x 979 x 219 = 7492028544

Therefore, the lowest common multiple of 128,728,672,979,657 is 7492028544.

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 728 x 672 x 979 x 657 = 40277145452544

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

979 : 1, 11, 89, 979

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,728,672,979,657, is 1.

Now, the common factors can be found like this.

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

728:2x 2x 2x 7x 13

672:2x 2x 2x 2x 2x 3x 7

979:11x 89

657:3x 3x 73

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 2x 2x 2x 2x 3x 7 = 5376

Therefore, the value for common factors is 5376.

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 = 40277145452544/(1x5376)

LCM = 40277145452544/5376

LCM = 7492028544

Thus, we can understand that the LCM of 128,728,672,979,657 is 7492028544.
