Given numbers are 121,858,720,276

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

The LCM of 121,858,720,276 is 26048880.

Find LCM of 121,858,720,276 with Prime Factorization

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

2 x 2 x 3 x 11 x 11 x 13 x 60 x 23 = 26048880

Therefore, the lowest common multiple of 121,858,720,276 is 26048880.

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 858 x 720 x 276 = 20630712960

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

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

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

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,858,720,276, is 1.

Now, the common factors can be found like this.

121:11x 11

858:2x 3x 11x 13

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

276:2x 2x 3x 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 2x 2x 3x 3x 11 = 792

Therefore, the value for common factors is 792.

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 = 20630712960/(1x792)

LCM = 20630712960/792

LCM = 26048880

Thus, we can understand that the LCM of 121,858,720,276 is 26048880.
