Given numbers are 121,321,979,853

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

The LCM of 121,321,979,853 is 2948692197.

Find LCM of 121,321,979,853 with Prime Factorization

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

11 x 11 x 321 x 89 x 853 = 2948692197

Therefore, the lowest common multiple of 121,321,979,853 is 2948692197.

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 321 x 979 x 853 = 32435614167

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

321 : 1, 3, 107, 321

979 : 1, 11, 89, 979

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,321,979,853, is 1.

Now, the common factors can be found like this.

121:11x 11

321:3x 107

979:11x 89

853:853

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

11 = 11

Therefore, the value for common factors is 11.

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 = 32435614167/(1x11)

LCM = 32435614167/11

LCM = 2948692197

Thus, we can understand that the LCM of 121,321,979,853 is 2948692197.
