Given numbers are 408,990,634,426

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

The LCM of 408,990,634,426 is 1515171240.

Find LCM of 408,990,634,426 with Prime Factorization

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

2 x 3 x 68 x 165 x 317 x 71 = 1515171240

Therefore, the lowest common multiple of 408,990,634,426 is 1515171240.

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.

408 x 990 x 634 x 426 = 109092329280

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.

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

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

634 : 1, 2, 317, 634

426 : 1, 2, 3, 6, 71, 142, 213, 426

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,990,634,426, is 2.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

990:2x 3x 3x 5x 11

634:2x 317

426:2x 3x 71

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 3 = 36

Therefore, the value for common factors is 36.

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 = 109092329280/(2x36)

LCM = 109092329280/72

LCM = 1515171240

Thus, we can understand that the LCM of 408,990,634,426 is 1515171240.
