Given numbers are 121,159,163,636

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

The LCM of 121,159,163,636 is 12543828.

Find LCM of 121,159,163,636 with Prime Factorization

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

3 x 53 x 121 x 1 x 163 x 4 = 12543828

Therefore, the lowest common multiple of 121,159,163,636 is 12543828.

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 159 x 163 x 636 = 1994468652

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

159 : 1, 3, 53, 159

163 : 1, 163

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,159,163,636, is 1.

Now, the common factors can be found like this.

121:11x 11

159:3x 53

163:163

636:2x 2x 3x 53

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

3x 53 = 159

Therefore, the value for common factors is 159.

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 = 1994468652/(1x159)

LCM = 1994468652/159

LCM = 12543828

Thus, we can understand that the LCM of 121,159,163,636 is 12543828.
