Given numbers are 422,646,422,953

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

The LCM of 422,646,422,953 is 129899618.

Find LCM of 422,646,422,953 with Prime Factorization

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

2 x 211 x 1 x 323 x 1 x 953 = 129899618

Therefore, the lowest common multiple of 422,646,422,953 is 129899618.

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 646 x 422 x 953 = 109635277592

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

422 : 1, 2, 211, 422

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,646,422,953, is 1.

Now, the common factors can be found like this.

422:2x 211

646:2x 17x 19

422:2x 211

953:953

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 211 = 844

Therefore, the value for common factors is 844.

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 = 109635277592/(1x844)

LCM = 109635277592/844

LCM = 129899618

Thus, we can understand that the LCM of 422,646,422,953 is 129899618.
