Given numbers are 523,575,417,990

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

The LCM of 523,575,417,990 is 8276553450.

Find LCM of 523,575,417,990 with Prime Factorization

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

3 x 5 x 523 x 115 x 139 x 66 = 8276553450

Therefore, the lowest common multiple of 523,575,417,990 is 8276553450.

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.

523 x 575 x 417 x 990 = 124148301750

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.

523 : 1, 523

575 : 1, 5, 23, 25, 115, 575

417 : 1, 3, 139, 417

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 523,575,417,990, is 1.

Now, the common factors can be found like this.

523:523

575:5x 5x 23

417:3x 139

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.

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 124148301750/(1x15)

LCM = 124148301750/15

LCM = 8276553450

Thus, we can understand that the LCM of 523,575,417,990 is 8276553450.
