Given numbers are 242,121,891,920

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

The LCM of 242,121,891,920 is 9016920.

Find LCM of 242,121,891,920 with Prime Factorization

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

2 x 11 x 11 x 1 x 1 x 81 x 460 = 9016920

Therefore, the lowest common multiple of 242,121,891,920 is 9016920.

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.

242 x 121 x 891 x 920 = 24003041040

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.

242 : 1, 2, 11, 22, 121, 242

121 : 1, 11, 121

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,121,891,920, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

121:11x 11

891:3x 3x 3x 3x 11

920:2x 2x 2x 5x 23

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

2x 11x 11x 11 = 2662

Therefore, the value for common factors is 2662.

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 = 24003041040/(1x2662)

LCM = 24003041040/2662

LCM = 9016920

Thus, we can understand that the LCM of 242,121,891,920 is 9016920.
