Given numbers are 121,856,552,807

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

The LCM of 121,856,552,807 is 1922474136.

Find LCM of 121,856,552,807 with Prime Factorization

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

2 x 2 x 2 x 3 x 121 x 107 x 23 x 269 = 1922474136

Therefore, the lowest common multiple of 121,856,552,807 is 1922474136.

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 856 x 552 x 807 = 46139379264

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

807 : 1, 3, 269, 807

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,856,552,807, is 1.

Now, the common factors can be found like this.

121:11x 11

856:2x 2x 2x 107

552:2x 2x 2x 3x 23

807:3x 269

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 3 = 24

Therefore, the value for common factors is 24.

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 = 46139379264/(1x24)

LCM = 46139379264/24

LCM = 1922474136

Thus, we can understand that the LCM of 121,856,552,807 is 1922474136.
