Given numbers are 990,408,497,771

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

The LCM of 990,408,497,771 is 8598716280.

Find LCM of 990,408,497,771 with Prime Factorization

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

2 x 3 x 165 x 68 x 497 x 257 = 8598716280

Therefore, the lowest common multiple of 990,408,497,771 is 8598716280.

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 408 x 497 x 771 = 154776893040

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

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

497 : 1, 7, 71, 497

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,408,497,771, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

408:2x 2x 2x 3x 17

497:7x 71

771:3x 257

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 3 = 18

Therefore, the value for common factors is 18.

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 = 154776893040/(1x18)

LCM = 154776893040/18

LCM = 8598716280

Thus, we can understand that the LCM of 990,408,497,771 is 8598716280.
