Calculate the LCM of 831,906,876,768

Given numbers are 831,906,876,768

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

The LCM of 831,906,876,768 is 2344988928.

Find LCM of 831,906,876,768 with Prime Factorization


2 831, 906, 876, 768
2 831, 453, 438, 384
3 831, 453, 219, 192
277, 151, 73, 64

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

2 x 2 x 3 x 277 x 151 x 73 x 64 = 2344988928

Therefore, the lowest common multiple of 831,906,876,768 is 2344988928.

LCM Formula to Find Lowest Common Multiple of 831,906,876,768

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 906 x 876 x 768 = 506517608448

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

906 : 1, 2, 3, 6, 151, 302, 453, 906

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,906,876,768, is 3.

Now, the common factors can be found like this.

831:3x 277

906:2x 3x 151

876:2x 2x 3x 73

768:2x 2x 2x 2x 2x 2x 2x 2x 3

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 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 506517608448/(3x72)

LCM = 506517608448/216

LCM = 2344988928

Thus, we can understand that the LCM of 831,906,876,768 is 2344988928.
