Calculate the LCM of 329,644,676,215

Given numbers are 329,644,676,215

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

The LCM of 329,644,676,215 is 1099787780.

Find LCM of 329,644,676,215 with Prime Factorization


2 329, 644, 676, 215
2 329, 322, 338, 215
7 329, 161, 169, 215
47, 23, 169, 215

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

2 x 2 x 7 x 47 x 23 x 169 x 215 = 1099787780

Therefore, the lowest common multiple of 329,644,676,215 is 1099787780.

LCM Formula to Find Lowest Common Multiple of 329,644,676,215

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.

329 x 644 x 676 x 215 = 30794057840

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.

329 : 1, 7, 47, 329

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,644,676,215, is 1.

Now, the common factors can be found like this.

329:7x 47

644:2x 2x 7x 23

676:2x 2x 13x 13

215:5x 43

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 30794057840/(1x28)

LCM = 30794057840/28

LCM = 1099787780

Thus, we can understand that the LCM of 329,644,676,215 is 1099787780.
