Calculate the LCM of 831,646,659,796

Given numbers are 831,646,659,796

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

The LCM of 831,646,659,796 is 140799796932.

Find LCM of 831,646,659,796 with Prime Factorization


2 831, 646, 659, 796
831, 323, 659, 398

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

2 x 831 x 323 x 659 x 398 = 140799796932

Therefore, the lowest common multiple of 831,646,659,796 is 140799796932.

LCM Formula to Find Lowest Common Multiple of 831,646,659,796

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 646 x 659 x 796 = 281599593864

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

659 : 1, 659

796 : 1, 2, 4, 199, 398, 796

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,646,659,796, is 1.

Now, the common factors can be found like this.

831:3x 277

646:2x 17x 19

659:659

796:2x 2x 199

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

2 = 2

Therefore, the value for common factors is 2.

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 = 281599593864/(1x2)

LCM = 281599593864/2

LCM = 140799796932

Thus, we can understand that the LCM of 831,646,659,796 is 140799796932.
