Given numbers are 638,187,110,668

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

The LCM of 638,187,110,668 is 18112820.

Find LCM of 638,187,110,668 with Prime Factorization

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

2 x 11 x 29 x 17 x 5 x 334 = 18112820

Therefore, the lowest common multiple of 638,187,110,668 is 18112820.

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 187 x 110 x 668 = 8766604880

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

187 : 1, 11, 17, 187

110 : 1, 2, 5, 10, 11, 22, 55, 110

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,187,110,668, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

187:11x 17

110:2x 5x 11

668:2x 2x 167

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 8766604880/(1x484)

LCM = 8766604880/484

LCM = 18112820

Thus, we can understand that the LCM of 638,187,110,668 is 18112820.
