Given numbers are 638,463,522,872

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

The LCM of 638,463,522,872 is 1159126056.

Find LCM of 638,463,522,872 with Prime Factorization

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

2 x 29 x 11 x 463 x 9 x 436 = 1159126056

Therefore, the lowest common multiple of 638,463,522,872 is 1159126056.

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.

638 x 463 x 522 x 872 = 134458622496

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.

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

463 : 1, 463

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,463,522,872, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

463:463

522:2x 3x 3x 29

872:2x 2x 2x 109

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 29 = 116

Therefore, the value for common factors is 116.

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 = 134458622496/(1x116)

LCM = 134458622496/116

LCM = 1159126056

Thus, we can understand that the LCM of 638,463,522,872 is 1159126056.
