Given numbers are 124,701,656,138,920

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

The LCM of 124,701,656,138,920 is 4918159920.

Find LCM of 124,701,656,138,920 with Prime Factorization

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

2 x 2 x 2 x 23 x 31 x 701 x 82 x 3 x 5 = 4918159920

Therefore, the lowest common multiple of 124,701,656,138,920 is 4918159920.

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.

124 x 701 x 656 x 138 x 920 = 7239531402240

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.

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

701 : 1, 701

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

138 : 1, 2, 3, 6, 23, 46, 69, 138

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 124,701,656,138,920, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

701:701

656:2x 2x 2x 2x 41

138:2x 3x 23

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 2x 2x 2x 2x 2x 23 = 1472

Therefore, the value for common factors is 1472.

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 = 7239531402240/(1x1472)

LCM = 7239531402240/1472

LCM = 4918159920

Thus, we can understand that the LCM of 124,701,656,138,920 is 4918159920.
