Given numbers are 212,817,872,638

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

The LCM of 212,817,872,638 is 12044952568.

Find LCM of 212,817,872,638 with Prime Factorization

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

2 x 2 x 53 x 817 x 218 x 319 = 12044952568

Therefore, the lowest common multiple of 212,817,872,638 is 12044952568.

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.

212 x 817 x 872 x 638 = 96359620544

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.

212 : 1, 2, 4, 53, 106, 212

817 : 1, 19, 43, 817

872 : 1, 2, 4, 8, 109, 218, 436, 872

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 212,817,872,638, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

817:19x 43

872:2x 2x 2x 109

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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 96359620544/(1x8)

LCM = 96359620544/8

LCM = 12044952568

Thus, we can understand that the LCM of 212,817,872,638 is 12044952568.
