Given numbers are 431,676,446,394

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

The LCM of 431,676,446,394 is 12799560436.

Find LCM of 431,676,446,394 with Prime Factorization

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

2 x 431 x 338 x 223 x 197 = 12799560436

Therefore, the lowest common multiple of 431,676,446,394 is 12799560436.

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.

431 x 676 x 446 x 394 = 51198241744

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.

431 : 1, 431

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

446 : 1, 2, 223, 446

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,676,446,394, is 1.

Now, the common factors can be found like this.

431:431

676:2x 2x 13x 13

446:2x 223

394:2x 197

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 = 51198241744/(1x4)

LCM = 51198241744/4

LCM = 12799560436

Thus, we can understand that the LCM of 431,676,446,394 is 12799560436.
