Given numbers are 646,436,992,163

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

The LCM of 646,436,992,163 is 5692831072.

Find LCM of 646,436,992,163 with Prime Factorization

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

2 x 2 x 323 x 109 x 248 x 163 = 5692831072

Therefore, the lowest common multiple of 646,436,992,163 is 5692831072.

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.

646 x 436 x 992 x 163 = 45542648576

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.

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

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

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,436,992,163, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

436:2x 2x 109

992:2x 2x 2x 2x 2x 31

163:163

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 = 45542648576/(1x8)

LCM = 45542648576/8

LCM = 5692831072

Thus, we can understand that the LCM of 646,436,992,163 is 5692831072.
