Given numbers are 191,671,720,985,955

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

The LCM of 191,671,720,985,955 is 18178356240.

Find LCM of 191,671,720,985,955 with Prime Factorization

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

5 x 191 x 1 x 671 x 144 x 197 x 1 = 18178356240

Therefore, the lowest common multiple of 191,671,720,985,955 is 18178356240.

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.

191 x 671 x 720 x 985 x 955 = 86801651046000

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.

191 : 1, 191

671 : 1, 11, 61, 671

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

985 : 1, 5, 197, 985

955 : 1, 5, 191, 955

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,671,720,985,955, is 1.

Now, the common factors can be found like this.

191:191

671:11x 61

720:2x 2x 2x 2x 3x 3x 5

985:5x 197

955:5x 191

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

5x 5x 191 = 4775

Therefore, the value for common factors is 4775.

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 = 86801651046000/(1x4775)

LCM = 86801651046000/4775

LCM = 18178356240

Thus, we can understand that the LCM of 191,671,720,985,955 is 18178356240.
