Given numbers are 472,657,936,990

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

The LCM of 472,657,936,990 is 221724360.

Find LCM of 472,657,936,990 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 59 x 73 x 13 x 55 = 221724360

Therefore, the lowest common multiple of 472,657,936,990 is 221724360.

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.

472 x 657 x 936 x 990 = 287354770560

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.

472 : 1, 2, 4, 8, 59, 118, 236, 472

657 : 1, 3, 9, 73, 219, 657

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,657,936,990, is 1.

Now, the common factors can be found like this.

472:2x 2x 2x 59

657:3x 3x 73

936:2x 2x 2x 3x 3x 13

990:2x 3x 3x 5x 11

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 3x 3x 3x 3 = 1296

Therefore, the value for common factors is 1296.

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 = 287354770560/(1x1296)

LCM = 287354770560/1296

LCM = 221724360

Thus, we can understand that the LCM of 472,657,936,990 is 221724360.
