Given numbers are 436,101,121,990

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

The LCM of 436,101,121,990 is 239776020.

Find LCM of 436,101,121,990 with Prime Factorization

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

2 x 11 x 218 x 101 x 11 x 45 = 239776020

Therefore, the lowest common multiple of 436,101,121,990 is 239776020.

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.

436 x 101 x 121 x 990 = 5275072440

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.

436 : 1, 2, 4, 109, 218, 436

101 : 1, 101

121 : 1, 11, 121

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,101,121,990, is 1.

Now, the common factors can be found like this.

436:2x 2x 109

101:101

121:11x 11

990:2x 3x 3x 5x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 5275072440/(1x22)

LCM = 5275072440/22

LCM = 239776020

Thus, we can understand that the LCM of 436,101,121,990 is 239776020.
