Given numbers are 856,977,924,642,638

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

The LCM of 856,977,924,642,638 is 5602454088.

Find LCM of 856,977,924,642,638 with Prime Factorization

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

2 x 2 x 3 x 11 x 107 x 2 x 977 x 7 x 1 x 29 = 5602454088

Therefore, the lowest common multiple of 856,977,924,642,638 is 5602454088.

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.

856 x 977 x 924 x 642 x 638 = 316516246155648

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

977 : 1, 977

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,977,924,642,638, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

977:977

924:2x 2x 3x 7x 11

642:2x 3x 107

638:2x 11x 29

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 2x 2x 3x 11x 107 = 56496

Therefore, the value for common factors is 56496.

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 = 316516246155648/(1x56496)

LCM = 316516246155648/56496

LCM = 5602454088

Thus, we can understand that the LCM of 856,977,924,642,638 is 5602454088.
