Given numbers are 121,656,879,420,770

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

The LCM of 121,656,879,420,770 is 2442002640.

Find LCM of 121,656,879,420,770 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 11 x 1 x 164 x 293 x 1 x 11 = 2442002640

Therefore, the lowest common multiple of 121,656,879,420,770 is 2442002640.

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 656 x 879 x 420 x 770 = 22564104393600

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

879 : 1, 3, 293, 879

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,656,879,420,770, is 1.

Now, the common factors can be found like this.

121:11x 11

656:2x 2x 2x 2x 41

879:3x 293

420:2x 2x 3x 5x 7

770:2x 5x 7x 11

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 3x 5x 7x 11 = 9240

Therefore, the value for common factors is 9240.

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 = 22564104393600/(1x9240)

LCM = 22564104393600/9240

LCM = 2442002640

Thus, we can understand that the LCM of 121,656,879,420,770 is 2442002640.
