Given numbers are 121,790,885,745,745

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

The LCM of 121,790,885,745,745 is 2520995070.

Find LCM of 121,790,885,745,745 with Prime Factorization

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

5 x 149 x 121 x 158 x 177 x 1 x 1 = 2520995070

Therefore, the lowest common multiple of 121,790,885,745,745 is 2520995070.

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 790 x 885 x 745 x 745 = 46953533178750

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

790 : 1, 2, 5, 10, 79, 158, 395, 790

885 : 1, 3, 5, 15, 59, 177, 295, 885

745 : 1, 5, 149, 745

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,790,885,745,745, is 1.

Now, the common factors can be found like this.

121:11x 11

790:2x 5x 79

885:3x 5x 59

745:5x 149

745:5x 149

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 5x 149 = 18625

Therefore, the value for common factors is 18625.

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 = 46953533178750/(1x18625)

LCM = 46953533178750/18625

LCM = 2520995070

Thus, we can understand that the LCM of 121,790,885,745,745 is 2520995070.
