Given numbers are 422,624,858,639

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

The LCM of 422,624,858,639 is 308488752.

Find LCM of 422,624,858,639 with Prime Factorization

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

2 x 3 x 13 x 211 x 8 x 11 x 213 = 308488752

Therefore, the lowest common multiple of 422,624,858,639 is 308488752.

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.

422 x 624 x 858 x 639 = 144372735936

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.

422 : 1, 2, 211, 422

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,624,858,639, is 1.

Now, the common factors can be found like this.

422:2x 211

624:2x 2x 2x 2x 3x 13

858:2x 3x 11x 13

639:3x 3x 71

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 3x 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 144372735936/(1x468)

LCM = 144372735936/468

LCM = 308488752

Thus, we can understand that the LCM of 422,624,858,639 is 308488752.
