Given numbers are 121,305,336,560

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

The LCM of 121,305,336,560 is 12400080.

Find LCM of 121,305,336,560 with Prime Factorization

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

2 x 2 x 2 x 2 x 5 x 7 x 121 x 61 x 3 x 1 = 12400080

Therefore, the lowest common multiple of 121,305,336,560 is 12400080.

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 305 x 336 x 560 = 6944044800

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

305 : 1, 5, 61, 305

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,305,336,560, is 1.

Now, the common factors can be found like this.

121:11x 11

305:5x 61

336:2x 2x 2x 2x 3x 7

560:2x 2x 2x 2x 5x 7

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 5x 7 = 560

Therefore, the value for common factors is 560.

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 = 6944044800/(1x560)

LCM = 6944044800/560

LCM = 12400080

Thus, we can understand that the LCM of 121,305,336,560 is 12400080.
