Given numbers are 485,328,990,440,660

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

The LCM of 485,328,990,440,660 is 15748920.

Find LCM of 485,328,990,440,660 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 11 x 97 x 41 x 1 x 1 x 3 = 15748920

Therefore, the lowest common multiple of 485,328,990,440,660 is 15748920.

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.

485 x 328 x 990 x 440 x 660 = 45734863680000

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.

485 : 1, 5, 97, 485

328 : 1, 2, 4, 8, 41, 82, 164, 328

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

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 485,328,990,440,660, is 1.

Now, the common factors can be found like this.

485:5x 97

328:2x 2x 2x 41

990:2x 3x 3x 5x 11

440:2x 2x 2x 5x 11

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 2x 2x 2x 2x 2x 3x 5x 5x 5x 11x 11 = 2904000

Therefore, the value for common factors is 2904000.

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 = 45734863680000/(1x2904000)

LCM = 45734863680000/2904000

LCM = 15748920

Thus, we can understand that the LCM of 485,328,990,440,660 is 15748920.
