Given numbers are 221,572,637,979

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

The LCM of 221,572,637,979 is 42406364.

Find LCM of 221,572,637,979 with Prime Factorization

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

11 x 13 x 17 x 4 x 49 x 89 = 42406364

Therefore, the lowest common multiple of 221,572,637,979 is 42406364.

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.

221 x 572 x 637 x 979 = 78833430676

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.

221 : 1, 13, 17, 221

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

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

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,572,637,979, is 1.

Now, the common factors can be found like this.

221:13x 17

572:2x 2x 11x 13

637:7x 7x 13

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.

11x 13x 13 = 1859

Therefore, the value for common factors is 1859.

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 = 78833430676/(1x1859)

LCM = 78833430676/1859

LCM = 42406364

Thus, we can understand that the LCM of 221,572,637,979 is 42406364.
