Given numbers are 128,260,511,979

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

The LCM of 128,260,511,979 is 4162238080.

Find LCM of 128,260,511,979 with Prime Factorization

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

2 x 2 x 32 x 65 x 511 x 979 = 4162238080

Therefore, the lowest common multiple of 128,260,511,979 is 4162238080.

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 260 x 511 x 979 = 16648952320

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

511 : 1, 7, 73, 511

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,260,511,979, is 1.

Now, the common factors can be found like this.

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

260:2x 2x 5x 13

511:7x 73

979:11x 89

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 16648952320/(1x4)

LCM = 16648952320/4

LCM = 4162238080

Thus, we can understand that the LCM of 128,260,511,979 is 4162238080.
