Given numbers are 638,187,533,664

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

The LCM of 638,187,533,664 is 1919264776.

Find LCM of 638,187,533,664 with Prime Factorization

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

2 x 11 x 29 x 17 x 533 x 332 = 1919264776

Therefore, the lowest common multiple of 638,187,533,664 is 1919264776.

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 533 x 664 = 42223825072

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

533 : 1, 13, 41, 533

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,187,533,664, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

187:11x 17

533:13x 41

664:2x 2x 2x 83

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 42223825072/(1x22)

LCM = 42223825072/22

LCM = 1919264776

Thus, we can understand that the LCM of 638,187,533,664 is 1919264776.
