Given numbers are 436,286,780,979

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

The LCM of 436,286,780,979 is 83234580.

Find LCM of 436,286,780,979 with Prime Factorization

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

2 x 2 x 11 x 13 x 109 x 1 x 15 x 89 = 83234580

Therefore, the lowest common multiple of 436,286,780,979 is 83234580.

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.

436 x 286 x 780 x 979 = 95220359520

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.

436 : 1, 2, 4, 109, 218, 436

286 : 1, 2, 11, 13, 22, 26, 143, 286

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,286,780,979, is 1.

Now, the common factors can be found like this.

436:2x 2x 109

286:2x 11x 13

780:2x 2x 3x 5x 13

979:11x 89

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 11x 13 = 1144

Therefore, the value for common factors is 1144.

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 = 95220359520/(1x1144)

LCM = 95220359520/1144

LCM = 83234580

Thus, we can understand that the LCM of 436,286,780,979 is 83234580.
