Given numbers are 491,788,864,394

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

The LCM of 491,788,864,394 is 83572128.

Find LCM of 491,788,864,394 with Prime Factorization

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

2 x 2 x 197 x 491 x 1 x 216 x 1 = 83572128

Therefore, the lowest common multiple of 491,788,864,394 is 83572128.

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.

491 x 788 x 864 x 394 = 131709673728

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.

491 : 1, 491

788 : 1, 2, 4, 197, 394, 788

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,788,864,394, is 1.

Now, the common factors can be found like this.

491:491

788:2x 2x 197

864:2x 2x 2x 2x 2x 3x 3x 3

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 2x 2x 197 = 1576

Therefore, the value for common factors is 1576.

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 = 131709673728/(1x1576)

LCM = 131709673728/1576

LCM = 83572128

Thus, we can understand that the LCM of 491,788,864,394 is 83572128.
