Given numbers are 639,508,638,914

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

The LCM of 639,508,638,914 is 47322911196.

Find LCM of 639,508,638,914 with Prime Factorization

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

2 x 639 x 254 x 319 x 457 = 47322911196

Therefore, the lowest common multiple of 639,508,638,914 is 47322911196.

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 508 x 638 x 914 = 189291644784

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

508 : 1, 2, 4, 127, 254, 508

638 : 1, 2, 11, 22, 29, 58, 319, 638

914 : 1, 2, 457, 914

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,508,638,914, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

508:2x 2x 127

638:2x 11x 29

914:2x 457

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 = 189291644784/(1x4)

LCM = 189291644784/4

LCM = 47322911196

Thus, we can understand that the LCM of 639,508,638,914 is 47322911196.
