Given numbers are 677,639,124,973,920

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

The LCM of 677,639,124,973,920 is 12004715945880.

Find LCM of 677,639,124,973,920 with Prime Factorization

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

2 x 2 x 677 x 639 x 31 x 973 x 230 = 12004715945880

Therefore, the lowest common multiple of 677,639,124,973,920 is 12004715945880.

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.

677 x 639 x 124 x 973 x 920 = 48018863783520

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.

677 : 1, 677

639 : 1, 3, 9, 71, 213, 639

124 : 1, 2, 4, 31, 62, 124

973 : 1, 7, 139, 973

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,639,124,973,920, is 1.

Now, the common factors can be found like this.

677:677

639:3x 3x 71

124:2x 2x 31

973:7x 139

920:2x 2x 2x 5x 23

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 = 48018863783520/(1x4)

LCM = 48018863783520/4

LCM = 12004715945880

Thus, we can understand that the LCM of 677,639,124,973,920 is 12004715945880.
