Given numbers are 121,836,628,430,520

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

The LCM of 121,836,628,430,520 is 8070685480.

Find LCM of 121,836,628,430,520 with Prime Factorization

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

2 x 2 x 5 x 11 x 11 x 19 x 157 x 43 x 26 = 8070685480

Therefore, the lowest common multiple of 121,836,628,430,520 is 8070685480.

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 836 x 628 x 430 x 520 = 14204406444800

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

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

628 : 1, 2, 4, 157, 314, 628

430 : 1, 2, 5, 10, 43, 86, 215, 430

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,836,628,430,520, is 1.

Now, the common factors can be found like this.

121:11x 11

836:2x 2x 11x 19

628:2x 2x 157

430:2x 5x 43

520:2x 2x 2x 5x 13

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 2x 2x 5x 11 = 1760

Therefore, the value for common factors is 1760.

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 = 14204406444800/(1x1760)

LCM = 14204406444800/1760

LCM = 8070685480

Thus, we can understand that the LCM of 121,836,628,430,520 is 8070685480.
