Given numbers are 990,865,660,506

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

The LCM of 990,865,660,506 is 7878420.

Find LCM of 990,865,660,506 with Prime Factorization

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

2 x 3 x 5 x 11 x 3 x 173 x 2 x 23 = 7878420

Therefore, the lowest common multiple of 990,865,660,506 is 7878420.

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 865 x 660 x 506 = 285986646000

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

865 : 1, 5, 173, 865

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

506 : 1, 2, 11, 22, 23, 46, 253, 506

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,865,660,506, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

865:5x 173

660:2x 2x 3x 5x 11

506:2x 11x 23

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 5x 5x 11x 11 = 36300

Therefore, the value for common factors is 36300.

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 = 285986646000/(1x36300)

LCM = 285986646000/36300

LCM = 7878420

Thus, we can understand that the LCM of 990,865,660,506 is 7878420.
