Given numbers are 637,338,115,663

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

The LCM of 637,338,115,663 is 97136130.

Find LCM of 637,338,115,663 with Prime Factorization

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

13 x 49 x 26 x 115 x 51 = 97136130

Therefore, the lowest common multiple of 637,338,115,663 is 97136130.

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.

637 x 338 x 115 x 663 = 16416005970

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.

637 : 1, 7, 13, 49, 91, 637

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

115 : 1, 5, 23, 115

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,338,115,663, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

338:2x 13x 13

115:5x 23

663:3x 13x 17

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 16416005970/(1x169)

LCM = 16416005970/169

LCM = 97136130

Thus, we can understand that the LCM of 637,338,115,663 is 97136130.
