Given numbers are 990,657,288,484

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

The LCM of 990,657,288,484 is 12719520.

Find LCM of 990,657,288,484 with Prime Factorization

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

2 x 2 x 3 x 3 x 11 x 5 x 73 x 8 x 11 = 12719520

Therefore, the lowest common multiple of 990,657,288,484 is 12719520.

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 657 x 288 x 484 = 90664738560

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

657 : 1, 3, 9, 73, 219, 657

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,657,288,484, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

657:3x 3x 73

288:2x 2x 2x 2x 2x 3x 3

484:2x 2x 11x 11

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 3x 3x 11 = 7128

Therefore, the value for common factors is 7128.

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 = 90664738560/(1x7128)

LCM = 90664738560/7128

LCM = 12719520

Thus, we can understand that the LCM of 990,657,288,484 is 12719520.
