Given numbers are 990,660,341,906

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

The LCM of 990,660,341,906 is 9268380.

Find LCM of 990,660,341,906 with Prime Factorization

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

2 x 3 x 5 x 11 x 3 x 2 x 31 x 151 = 9268380

Therefore, the lowest common multiple of 990,660,341,906 is 9268380.

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 660 x 341 x 906 = 201865316400

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

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

341 : 1, 11, 31, 341

906 : 1, 2, 3, 6, 151, 302, 453, 906

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,660,341,906, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

660:2x 2x 3x 5x 11

341:11x 31

906:2x 3x 151

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 5x 11x 11 = 21780

Therefore, the value for common factors is 21780.

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 = 201865316400/(1x21780)

LCM = 201865316400/21780

LCM = 9268380

Thus, we can understand that the LCM of 990,660,341,906 is 9268380.
