Given numbers are 928,988,815,388,121

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

The LCM of 928,988,815,388,121 is 2192601176480.

Find LCM of 928,988,815,388,121 with Prime Factorization

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

2 x 2 x 232 x 247 x 815 x 97 x 121 = 2192601176480

Therefore, the lowest common multiple of 928,988,815,388,121 is 2192601176480.

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.

928 x 988 x 815 x 388 x 121 = 35081618823680

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.

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

815 : 1, 5, 163, 815

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

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,988,815,388,121, is 1.

Now, the common factors can be found like this.

928:2x 2x 2x 2x 2x 29

988:2x 2x 13x 19

815:5x 163

388:2x 2x 97

121:11x 11

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 2 = 16

Therefore, the value for common factors is 16.

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 = 35081618823680/(1x16)

LCM = 35081618823680/16

LCM = 2192601176480

Thus, we can understand that the LCM of 928,988,815,388,121 is 2192601176480.
