Given numbers are 389,391,517,990

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

The LCM of 389,391,517,990 is 7077166470.

Find LCM of 389,391,517,990 with Prime Factorization

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

11 x 389 x 391 x 47 x 90 = 7077166470

Therefore, the lowest common multiple of 389,391,517,990 is 7077166470.

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.

389 x 391 x 517 x 990 = 77848831170

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.

389 : 1, 389

391 : 1, 17, 23, 391

517 : 1, 11, 47, 517

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 389,391,517,990, is 1.

Now, the common factors can be found like this.

389:389

391:17x 23

517:11x 47

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 77848831170/(1x11)

LCM = 77848831170/11

LCM = 7077166470

Thus, we can understand that the LCM of 389,391,517,990 is 7077166470.
