Given numbers are 990,473,979,728

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

The LCM of 990,473,979,728 is 1379097720.

Find LCM of 990,473,979,728 with Prime Factorization

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

2 x 11 x 45 x 43 x 89 x 364 = 1379097720

Therefore, the lowest common multiple of 990,473,979,728 is 1379097720.

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.

990 x 473 x 979 x 728 = 333741648240

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

473 : 1, 11, 43, 473

979 : 1, 11, 89, 979

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,473,979,728, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

473:11x 43

979:11x 89

728:2x 2x 2x 7x 13

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 11 = 242

Therefore, the value for common factors is 242.

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 = 333741648240/(1x242)

LCM = 333741648240/242

LCM = 1379097720

Thus, we can understand that the LCM of 990,473,979,728 is 1379097720.
