Given numbers are 388,644,579,989,557

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

The LCM of 388,644,579,989,557 is 866283048372.

Find LCM of 388,644,579,989,557 with Prime Factorization

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

2 x 2 x 23 x 97 x 7 x 579 x 43 x 557 = 866283048372

Therefore, the lowest common multiple of 388,644,579,989,557 is 866283048372.

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.

388 x 644 x 579 x 989 x 557 = 79698040450224

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.

388 : 1, 2, 4, 97, 194, 388

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

579 : 1, 3, 193, 579

989 : 1, 23, 43, 989

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,644,579,989,557, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

644:2x 2x 7x 23

579:3x 193

989:23x 43

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 2x 23 = 92

Therefore, the value for common factors is 92.

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 = 79698040450224/(1x92)

LCM = 79698040450224/92

LCM = 866283048372

Thus, we can understand that the LCM of 388,644,579,989,557 is 866283048372.
