Given numbers are 990,390,554,447,857

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

The LCM of 990,390,554,447,857 is 455224268070.

Find LCM of 990,390,554,447,857 with Prime Factorization

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

2 x 3 x 5 x 33 x 13 x 277 x 149 x 857 = 455224268070

Therefore, the lowest common multiple of 990,390,554,447,857 is 455224268070.

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 390 x 554 x 447 x 857 = 81940368252600

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

554 : 1, 2, 277, 554

447 : 1, 3, 149, 447

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,390,554,447,857, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

390:2x 3x 5x 13

554:2x 277

447:3x 149

857:857

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 5 = 180

Therefore, the value for common factors is 180.

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 = 81940368252600/(1x180)

LCM = 81940368252600/180

LCM = 455224268070

Thus, we can understand that the LCM of 990,390,554,447,857 is 455224268070.
