Given numbers are 639,992,713,676,857

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

The LCM of 639,992,713,676,857 is 2111581716192.

Find LCM of 639,992,713,676,857 with Prime Factorization

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

2 x 2 x 31 x 639 x 8 x 23 x 169 x 857 = 2111581716192

Therefore, the lowest common multiple of 639,992,713,676,857 is 2111581716192.

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.

639 x 992 x 713 x 676 x 857 = 261836132807808

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.

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

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

713 : 1, 23, 31, 713

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,992,713,676,857, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

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

713:23x 31

676:2x 2x 13x 13

857:857

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 31 = 124

Therefore, the value for common factors is 124.

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 = 261836132807808/(1x124)

LCM = 261836132807808/124

LCM = 2111581716192

Thus, we can understand that the LCM of 639,992,713,676,857 is 2111581716192.
