Given numbers are 856,638,213,676

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

The LCM of 856,638,213,676 is 9829484808.

Find LCM of 856,638,213,676 with Prime Factorization

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

2 x 2 x 214 x 319 x 213 x 169 = 9829484808

Therefore, the lowest common multiple of 856,638,213,676 is 9829484808.

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 638 x 213 x 676 = 78635878464

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

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

213 : 1, 3, 71, 213

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,638,213,676, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

638:2x 11x 29

213:3x 71

676:2x 2x 13x 13

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 = 78635878464/(1x8)

LCM = 78635878464/8

LCM = 9829484808

Thus, we can understand that the LCM of 856,638,213,676 is 9829484808.
