Calculate the LCM of 831,831,108,115

Given numbers are 831,831,108,115

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

The LCM of 831,831,108,115 is 3440340.

Find LCM of 831,831,108,115 with Prime Factorization


3 831, 831, 108, 115
277 277, 277, 36, 115
1, 1, 36, 115

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

3 x 277 x 1 x 1 x 36 x 115 = 3440340

Therefore, the lowest common multiple of 831,831,108,115 is 3440340.

LCM Formula to Find Lowest Common Multiple of 831,831,108,115

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.

831 x 831 x 108 x 115 = 8576767620

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.

831 : 1, 3, 277, 831

831 : 1, 3, 277, 831

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,831,108,115, is 1.

Now, the common factors can be found like this.

831:3x 277

831:3x 277

108:2x 2x 3x 3x 3

115:5x 23

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

3x 3x 277 = 2493

Therefore, the value for common factors is 2493.

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 = 8576767620/(1x2493)

LCM = 8576767620/2493

LCM = 3440340

Thus, we can understand that the LCM of 831,831,108,115 is 3440340.
