Given numbers are 660,411,990,830

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

The LCM of 660,411,990,830 is 22514580.

Find LCM of 660,411,990,830 with Prime Factorization

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

2 x 3 x 5 x 11 x 2 x 137 x 3 x 83 = 22514580

Therefore, the lowest common multiple of 660,411,990,830 is 22514580.

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.

660 x 411 x 990 x 830 = 222894342000

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.

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

411 : 1, 3, 137, 411

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

830 : 1, 2, 5, 10, 83, 166, 415, 830

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,411,990,830, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

411:3x 137

990:2x 3x 3x 5x 11

830:2x 5x 83

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 5x 11 = 9900

Therefore, the value for common factors is 9900.

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 = 222894342000/(1x9900)

LCM = 222894342000/9900

LCM = 22514580

Thus, we can understand that the LCM of 660,411,990,830 is 22514580.
