Given numbers are 660,121,548,407

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

The LCM of 660,121,548,407 is 36800940.

Find LCM of 660,121,548,407 with Prime Factorization

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

2 x 2 x 11 x 15 x 11 x 137 x 37 = 36800940

Therefore, the lowest common multiple of 660,121,548,407 is 36800940.

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.

660 x 121 x 548 x 407 = 17811654960

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

121 : 1, 11, 121

548 : 1, 2, 4, 137, 274, 548

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,121,548,407, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

121:11x 11

548:2x 2x 137

407:11x 37

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 17811654960/(1x484)

LCM = 17811654960/484

LCM = 36800940

Thus, we can understand that the LCM of 660,121,548,407 is 36800940.
