Given numbers are 639,411,816,249,572

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

The LCM of 639,411,816,249,572 is 282621019824.

Find LCM of 639,411,816,249,572 with Prime Factorization

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

2 x 2 x 3 x 213 x 137 x 68 x 83 x 143 = 282621019824

Therefore, the lowest common multiple of 639,411,816,249,572 is 282621019824.

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.

639 x 411 x 816 x 249 x 572 = 30523070140992

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.

639 : 1, 3, 9, 71, 213, 639

411 : 1, 3, 137, 411

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

249 : 1, 3, 83, 249

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,411,816,249,572, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

411:3x 137

816:2x 2x 2x 2x 3x 17

249:3x 83

572:2x 2x 11x 13

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 30523070140992/(1x108)

LCM = 30523070140992/108

LCM = 282621019824

Thus, we can understand that the LCM of 639,411,816,249,572 is 282621019824.
