Given numbers are 817,916,146,638

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

The LCM of 817,916,146,638 is 17427338764.

Find LCM of 817,916,146,638 with Prime Factorization

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

2 x 817 x 458 x 73 x 319 = 17427338764

Therefore, the lowest common multiple of 817,916,146,638 is 17427338764.

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.

817 x 916 x 146 x 638 = 69709355056

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.

817 : 1, 19, 43, 817

916 : 1, 2, 4, 229, 458, 916

146 : 1, 2, 73, 146

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 817,916,146,638, is 1.

Now, the common factors can be found like this.

817:19x 43

916:2x 2x 229

146:2x 73

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 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 = 69709355056/(1x4)

LCM = 69709355056/4

LCM = 17427338764

Thus, we can understand that the LCM of 817,916,146,638 is 17427338764.
