Calculate the LCM of 385,123,831,205

Given numbers are 385,123,831,205

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

The LCM of 385,123,831,205 is 13117335.

Find LCM of 385,123,831,205 with Prime Factorization


3 385, 123, 831, 205
5 385, 41, 277, 205
41 77, 41, 277, 41
77, 1, 277, 1

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

3 x 5 x 41 x 77 x 1 x 277 x 1 = 13117335

Therefore, the lowest common multiple of 385,123,831,205 is 13117335.

LCM Formula to Find Lowest Common Multiple of 385,123,831,205

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.

385 x 123 x 831 x 205 = 8067161025

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

123 : 1, 3, 41, 123

831 : 1, 3, 277, 831

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,123,831,205, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

123:3x 41

831:3x 277

205:5x 41

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 41 = 615

Therefore, the value for common factors is 615.

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 = 8067161025/(1x615)

LCM = 8067161025/615

LCM = 13117335

Thus, we can understand that the LCM of 385,123,831,205 is 13117335.
