Given numbers are 990,815,199,660

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

The LCM of 990,815,199,660 is 64225260.

Find LCM of 990,815,199,660 with Prime Factorization

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

2 x 3 x 5 x 11 x 3 x 163 x 199 x 2 = 64225260

Therefore, the lowest common multiple of 990,815,199,660 is 64225260.

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 815 x 199 x 660 = 105971679000

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

815 : 1, 5, 163, 815

199 : 1, 199

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,815,199,660, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

815:5x 163

199:199

660:2x 2x 3x 5x 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 3x 5x 5x 11 = 1650

Therefore, the value for common factors is 1650.

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 = 105971679000/(1x1650)

LCM = 105971679000/1650

LCM = 64225260

Thus, we can understand that the LCM of 990,815,199,660 is 64225260.
