Given numbers are 855,277,624,638

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

The LCM of 855,277,624,638 is 15714475920.

Find LCM of 855,277,624,638 with Prime Factorization

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

2 x 3 x 285 x 277 x 104 x 319 = 15714475920

Therefore, the lowest common multiple of 855,277,624,638 is 15714475920.

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 277 x 624 x 638 = 94286855520

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

277 : 1, 277

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

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 855,277,624,638, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

277:277

624:2x 2x 2x 2x 3x 13

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 3 = 6

Therefore, the value for common factors is 6.

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 = 94286855520/(1x6)

LCM = 94286855520/6

LCM = 15714475920

Thus, we can understand that the LCM of 855,277,624,638 is 15714475920.
