Given numbers are 121,854,671,997

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

The LCM of 121,854,671,997 is 103023998.

Find LCM of 121,854,671,997 with Prime Factorization

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

11 x 61 x 11 x 14 x 1 x 997 = 103023998

Therefore, the lowest common multiple of 121,854,671,997 is 103023998.

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 854 x 671 x 997 = 69129102658

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

854 : 1, 2, 7, 14, 61, 122, 427, 854

671 : 1, 11, 61, 671

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,854,671,997, is 1.

Now, the common factors can be found like this.

121:11x 11

854:2x 7x 61

671:11x 61

997:997

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

11x 61 = 671

Therefore, the value for common factors is 671.

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 = 69129102658/(1x671)

LCM = 69129102658/671

LCM = 103023998

Thus, we can understand that the LCM of 121,854,671,997 is 103023998.
