Calculate the LCM of 813,813,388,625

Given numbers are 813,813,388,625

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

The LCM of 813,813,388,625 is 197152500.

Find LCM of 813,813,388,625 with Prime Factorization


3 813, 813, 388, 625
271 271, 271, 388, 625
1, 1, 388, 625

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

3 x 271 x 1 x 1 x 388 x 625 = 197152500

Therefore, the lowest common multiple of 813,813,388,625 is 197152500.

LCM Formula to Find Lowest Common Multiple of 813,813,388,625

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.

813 x 813 x 388 x 625 = 160284982500

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.

813 : 1, 3, 271, 813

813 : 1, 3, 271, 813

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

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,813,388,625, is 1.

Now, the common factors can be found like this.

813:3x 271

813:3x 271

388:2x 2x 97

625:5x 5x 5x 5

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

3x 271 = 813

Therefore, the value for common factors is 813.

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 = 160284982500/(1x813)

LCM = 160284982500/813

LCM = 197152500

Thus, we can understand that the LCM of 813,813,388,625 is 197152500.
