Given numbers are 635,127,442,638

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

The LCM of 635,127,442,638 is 89533730.

Find LCM of 635,127,442,638 with Prime Factorization

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

2 x 127 x 5 x 1 x 221 x 319 = 89533730

Therefore, the lowest common multiple of 635,127,442,638 is 89533730.

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.

635 x 127 x 442 x 638 = 22741567420

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.

635 : 1, 5, 127, 635

127 : 1, 127

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,127,442,638, is 1.

Now, the common factors can be found like this.

635:5x 127

127:127

442:2x 13x 17

638:2x 11x 29

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 22741567420/(1x254)

LCM = 22741567420/254

LCM = 89533730

Thus, we can understand that the LCM of 635,127,442,638 is 89533730.
