Given numbers are 990,922,789,612

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

The LCM of 990,922,789,612 is 4081039380.

Find LCM of 990,922,789,612 with Prime Factorization

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

2 x 3 x 3 x 55 x 461 x 263 x 34 = 4081039380

Therefore, the lowest common multiple of 990,922,789,612 is 4081039380.

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 922 x 789 x 612 = 440752253040

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

922 : 1, 2, 461, 922

789 : 1, 3, 263, 789

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,922,789,612, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

922:2x 461

789:3x 263

612:2x 2x 3x 3x 17

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 440752253040/(1x108)

LCM = 440752253040/108

LCM = 4081039380

Thus, we can understand that the LCM of 990,922,789,612 is 4081039380.
