Calculate the LCM of 390,725,793,639

Given numbers are 390,725,793,639

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

The LCM of 390,725,793,639 is 734754150.

Find LCM of 390,725,793,639 with Prime Factorization


3 390, 725, 793, 639
5 130, 725, 793, 213
13 26, 145, 793, 213
2, 145, 61, 213

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

3 x 5 x 13 x 2 x 145 x 61 x 213 = 734754150

Therefore, the lowest common multiple of 390,725,793,639 is 734754150.

LCM Formula to Find Lowest Common Multiple of 390,725,793,639

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.

390 x 725 x 793 x 639 = 143277059250

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

725 : 1, 5, 25, 29, 145, 725

793 : 1, 13, 61, 793

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,725,793,639, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

725:5x 5x 29

793:13x 61

639:3x 3x 71

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

3x 5x 13 = 195

Therefore, the value for common factors is 195.

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 = 143277059250/(1x195)

LCM = 143277059250/195

LCM = 734754150

Thus, we can understand that the LCM of 390,725,793,639 is 734754150.
