Given numbers are 646,642,718,878

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

The LCM of 646,642,718,878 is 32681088966.

Find LCM of 646,642,718,878 with Prime Factorization

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

2 x 323 x 321 x 359 x 439 = 32681088966

Therefore, the lowest common multiple of 646,642,718,878 is 32681088966.

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 642 x 718 x 878 = 261448711728

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

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

718 : 1, 2, 359, 718

878 : 1, 2, 439, 878

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,642,718,878, is 2.

Now, the common factors can be found like this.

646:2x 17x 19

642:2x 3x 107

718:2x 359

878:2x 439

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 261448711728/(2x4)

LCM = 261448711728/8

LCM = 32681088966

Thus, we can understand that the LCM of 646,642,718,878 is 32681088966.
