Given numbers are 676,389,614,638

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

The LCM of 676,389,614,638 is 25752853412.

Find LCM of 676,389,614,638 with Prime Factorization

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

2 x 338 x 389 x 307 x 319 = 25752853412

Therefore, the lowest common multiple of 676,389,614,638 is 25752853412.

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.

676 x 389 x 614 x 638 = 103011413648

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

389 : 1, 389

614 : 1, 2, 307, 614

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 676,389,614,638, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

389:389

614:2x 307

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 2 = 4

Therefore, the value for common factors is 4.

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 = 103011413648/(1x4)

LCM = 103011413648/4

LCM = 25752853412

Thus, we can understand that the LCM of 676,389,614,638 is 25752853412.
