Given numbers are 666,722,166,638

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

The LCM of 666,722,166,638 is 6365759202.

Find LCM of 666,722,166,638 with Prime Factorization

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

2 x 333 x 361 x 83 x 319 = 6365759202

Therefore, the lowest common multiple of 666,722,166,638 is 6365759202.

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.

666 x 722 x 166 x 638 = 50926073616

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.

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

722 : 1, 2, 19, 38, 361, 722

166 : 1, 2, 83, 166

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,722,166,638, is 2.

Now, the common factors can be found like this.

666:2x 3x 3x 37

722:2x 19x 19

166:2x 83

638:2x 11x 29

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 = 50926073616/(2x4)

LCM = 50926073616/8

LCM = 6365759202

Thus, we can understand that the LCM of 666,722,166,638 is 6365759202.
