Given numbers are 627,415,338,638

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

The LCM of 627,415,338,638 is 2550529410.

Find LCM of 627,415,338,638 with Prime Factorization

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

2 x 11 x 57 x 415 x 169 x 29 = 2550529410

Therefore, the lowest common multiple of 627,415,338,638 is 2550529410.

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.

627 x 415 x 338 x 638 = 56111647020

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.

627 : 1, 3, 11, 19, 33, 57, 209, 627

415 : 1, 5, 83, 415

338 : 1, 2, 13, 26, 169, 338

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 627,415,338,638, is 1.

Now, the common factors can be found like this.

627:3x 11x 19

415:5x 83

338:2x 13x 13

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 11 = 22

Therefore, the value for common factors is 22.

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 = 56111647020/(1x22)

LCM = 56111647020/22

LCM = 2550529410

Thus, we can understand that the LCM of 627,415,338,638 is 2550529410.
