Given numbers are 990,278,579,392

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

The LCM of 990,278,579,392 is 5205511080.

Find LCM of 990,278,579,392 with Prime Factorization

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

2 x 3 x 165 x 139 x 193 x 196 = 5205511080

Therefore, the lowest common multiple of 990,278,579,392 is 5205511080.

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 278 x 579 x 392 = 62466132960

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

278 : 1, 2, 139, 278

579 : 1, 3, 193, 579

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,278,579,392, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

278:2x 139

579:3x 193

392:2x 2x 2x 7x 7

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 3 = 12

Therefore, the value for common factors is 12.

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 = 62466132960/(1x12)

LCM = 62466132960/12

LCM = 5205511080

Thus, we can understand that the LCM of 990,278,579,392 is 5205511080.
