Given numbers are 638,963,808

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

The LCM of 638,963,808 is 248215176.

Find LCM of 638,963,808 with Prime Factorization

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

2 x 319 x 963 x 404 = 248215176

Therefore, the lowest common multiple of 638,963,808 is 248215176.

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.

638 x 963 x 808 = 496430352

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.

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

963 : 1, 3, 9, 107, 321, 963

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,963,808, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

963:3x 3x 107

808:2x 2x 2x 101

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 496430352/(1x2)

LCM = 496430352/2

LCM = 248215176

Thus, we can understand that the LCM of 638,963,808 is 248215176.
