Given numbers are 442,408,623,990

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

The LCM of 442,408,623,990 is 545224680.

Find LCM of 442,408,623,990 with Prime Factorization

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

2 x 3 x 17 x 13 x 4 x 623 x 165 = 545224680

Therefore, the lowest common multiple of 442,408,623,990 is 545224680.

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.

442 x 408 x 623 x 990 = 111225834720

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

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

623 : 1, 7, 89, 623

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 442,408,623,990, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

408:2x 2x 2x 3x 17

623:7x 89

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 3x 17 = 204

Therefore, the value for common factors is 204.

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 = 111225834720/(1x204)

LCM = 111225834720/204

LCM = 545224680

Thus, we can understand that the LCM of 442,408,623,990 is 545224680.
