Given numbers are 919,517,154,638

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

The LCM of 919,517,154,638 is 192899938.

Find LCM of 919,517,154,638 with Prime Factorization

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

2 x 11 x 919 x 47 x 7 x 29 = 192899938

Therefore, the lowest common multiple of 919,517,154,638 is 192899938.

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.

919 x 517 x 154 x 638 = 46681784996

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.

919 : 1, 919

517 : 1, 11, 47, 517

154 : 1, 2, 7, 11, 14, 22, 77, 154

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,517,154,638, is 1.

Now, the common factors can be found like this.

919:919

517:11x 47

154:2x 7x 11

638:2x 11x 29

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 46681784996/(1x242)

LCM = 46681784996/242

LCM = 192899938

Thus, we can understand that the LCM of 919,517,154,638 is 192899938.
