Given numbers are 481,537,990,642

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

The LCM of 481,537,990,642 is 9120467070.

Find LCM of 481,537,990,642 with Prime Factorization

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

2 x 3 x 481 x 179 x 165 x 107 = 9120467070

Therefore, the lowest common multiple of 481,537,990,642 is 9120467070.

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.

481 x 537 x 990 x 642 = 164168407260

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.

481 : 1, 13, 37, 481

537 : 1, 3, 179, 537

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,537,990,642, is 1.

Now, the common factors can be found like this.

481:13x 37

537:3x 179

990:2x 3x 3x 5x 11

642:2x 3x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 164168407260/(1x18)

LCM = 164168407260/18

LCM = 9120467070

Thus, we can understand that the LCM of 481,537,990,642 is 9120467070.
