Given numbers are 121,968,535,920

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

The LCM of 121,968,535,920 is 11911240.

Find LCM of 121,968,535,920 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 11 x 1 x 1 x 107 x 23 = 11911240

Therefore, the lowest common multiple of 121,968,535,920 is 11911240.

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 968 x 535 x 920 = 57650401600

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

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

535 : 1, 5, 107, 535

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,968,535,920, is 1.

Now, the common factors can be found like this.

121:11x 11

968:2x 2x 2x 11x 11

535:5x 107

920:2x 2x 2x 5x 23

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 2x 5x 11x 11 = 4840

Therefore, the value for common factors is 4840.

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 = 57650401600/(1x4840)

LCM = 57650401600/4840

LCM = 11911240

Thus, we can understand that the LCM of 121,968,535,920 is 11911240.
