Given numbers are 131,121,424,636

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

The LCM of 131,121,424,636 is 20162472.

Find LCM of 131,121,424,636 with Prime Factorization

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

2 x 2 x 53 x 131 x 121 x 2 x 3 = 20162472

Therefore, the lowest common multiple of 131,121,424,636 is 20162472.

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.

131 x 121 x 424 x 636 = 4274444064

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.

131 : 1, 131

121 : 1, 11, 121

424 : 1, 2, 4, 8, 53, 106, 212, 424

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 131,121,424,636, is 1.

Now, the common factors can be found like this.

131:131

121:11x 11

424:2x 2x 2x 53

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.

2x 2x 53 = 212

Therefore, the value for common factors is 212.

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 = 4274444064/(1x212)

LCM = 4274444064/212

LCM = 20162472

Thus, we can understand that the LCM of 131,121,424,636 is 20162472.
