Given numbers are 121,155,135,166

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

The LCM of 121,155,135,166 is 84059910.

Find LCM of 121,155,135,166 with Prime Factorization

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

5 x 121 x 31 x 27 x 166 = 84059910

Therefore, the lowest common multiple of 121,155,135,166 is 84059910.

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.

121 x 155 x 135 x 166 = 420299550

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.

121 : 1, 11, 121

155 : 1, 5, 31, 155

135 : 1, 3, 5, 9, 15, 27, 45, 135

166 : 1, 2, 83, 166

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,155,135,166, is 1.

Now, the common factors can be found like this.

121:11x 11

155:5x 31

135:3x 3x 3x 5

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.

5 = 5

Therefore, the value for common factors is 5.

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 = 420299550/(1x5)

LCM = 420299550/5

LCM = 84059910

Thus, we can understand that the LCM of 121,155,135,166 is 84059910.

Here are some samples of LCM of two or more Numbers calculations.
