Calculate the LCM of 817,637,936,916

Given numbers are 817,637,936,916

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

The LCM of 817,637,936,916 is 8580833352.

Find LCM of 817,637,936,916 with Prime Factorization


2 817, 637, 936, 916
2 817, 637, 468, 458
13 817, 637, 234, 229
817, 49, 18, 229

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

2 x 2 x 13 x 817 x 49 x 18 x 229 = 8580833352

Therefore, the lowest common multiple of 817,637,936,916 is 8580833352.

LCM Formula to Find Lowest Common Multiple of 817,637,936,916

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 637 x 936 x 916 = 446203334304

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

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

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,637,936,916, is 1.

Now, the common factors can be found like this.

817:19x 43

637:7x 7x 13

936:2x 2x 2x 3x 3x 13

916:2x 2x 229

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 13 = 52

Therefore, the value for common factors is 52.

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 = 446203334304/(1x52)

LCM = 446203334304/52

LCM = 8580833352

Thus, we can understand that the LCM of 817,637,936,916 is 8580833352.
