Given numbers are 168,638,166

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

The LCM of 168,638,166 is 4448136.

Find LCM of 168,638,166 with Prime Factorization

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

2 x 84 x 319 x 83 = 4448136

Therefore, the lowest common multiple of 168,638,166 is 4448136.

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.

168 x 638 x 166 = 17792544

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

166 : 1, 2, 83, 166

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,638,166, is 2.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

638:2x 11x 29

166:2x 83

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

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 = 17792544/(2x2)

LCM = 17792544/4

LCM = 4448136

Thus, we can understand that the LCM of 168,638,166 is 4448136.
