Calculate the LCM of 631,386,388,389,913

Given numbers are 631,386,388,389,913

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

The LCM of 631,386,388,389,913 is 16781808953228.

Find LCM of 631,386,388,389,913 with Prime Factorization


2 631, 386, 388, 389, 913
631, 193, 194, 389, 913

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

2 x 631 x 193 x 194 x 389 x 913 = 16781808953228

Therefore, the lowest common multiple of 631,386,388,389,913 is 16781808953228.

LCM Formula to Find Lowest Common Multiple of 631,386,388,389,913

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.

631 x 386 x 388 x 389 x 913 = 33563617906456

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.

631 : 1, 631

386 : 1, 2, 193, 386

388 : 1, 2, 4, 97, 194, 388

389 : 1, 389

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,386,388,389,913, is 1.

Now, the common factors can be found like this.

631:631

386:2x 193

388:2x 2x 97

389:389

913:11x 83

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

2 = 2

Therefore, the value for common factors is 2.

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 = 33563617906456/(1x2)

LCM = 33563617906456/2

LCM = 16781808953228

Thus, we can understand that the LCM of 631,386,388,389,913 is 16781808953228.
