Given numbers are 331,572,990,636

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

The LCM of 331,572,990,636 is 451556820.

Find LCM of 331,572,990,636 with Prime Factorization

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

2 x 2 x 3 x 11 x 331 x 13 x 15 x 53 = 451556820

Therefore, the lowest common multiple of 331,572,990,636 is 451556820.

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.

331 x 572 x 990 x 636 = 119211000480

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.

331 : 1, 331

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,572,990,636, is 1.

Now, the common factors can be found like this.

331:331

572:2x 2x 11x 13

990:2x 3x 3x 5x 11

636:2x 2x 3x 53

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 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 119211000480/(1x264)

LCM = 119211000480/264

LCM = 451556820

Thus, we can understand that the LCM of 331,572,990,636 is 451556820.
