Given numbers are 568,290,491,990

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

The LCM of 568,290,491,990 is 4003437240.

Find LCM of 568,290,491,990 with Prime Factorization

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

2 x 5 x 284 x 29 x 491 x 99 = 4003437240

Therefore, the lowest common multiple of 568,290,491,990 is 4003437240.

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.

568 x 290 x 491 x 990 = 80068744800

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.

568 : 1, 2, 4, 8, 71, 142, 284, 568

290 : 1, 2, 5, 10, 29, 58, 145, 290

491 : 1, 491

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,290,491,990, is 1.

Now, the common factors can be found like this.

568:2x 2x 2x 71

290:2x 5x 29

491:491

990:2x 3x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 80068744800/(1x20)

LCM = 80068744800/20

LCM = 4003437240

Thus, we can understand that the LCM of 568,290,491,990 is 4003437240.
