Given numbers are 855,312,634,426

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

The LCM of 855,312,634,426 is 2001322440.

Find LCM of 855,312,634,426 with Prime Factorization

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

2 x 3 x 285 x 52 x 317 x 71 = 2001322440

Therefore, the lowest common multiple of 855,312,634,426 is 2001322440.

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.

855 x 312 x 634 x 426 = 72047607840

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

634 : 1, 2, 317, 634

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,312,634,426, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

312:2x 2x 2x 3x 13

634:2x 317

426:2x 3x 71

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 72047607840/(1x36)

LCM = 72047607840/36

LCM = 2001322440

Thus, we can understand that the LCM of 855,312,634,426 is 2001322440.
