Calculate the LCM of 831,866,677,784

Given numbers are 831,866,677,784

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

The LCM of 831,866,677,784 is 190982534064.

Find LCM of 831,866,677,784 with Prime Factorization


2 831, 866, 677, 784
831, 433, 677, 392

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

2 x 831 x 433 x 677 x 392 = 190982534064

Therefore, the lowest common multiple of 831,866,677,784 is 190982534064.

LCM Formula to Find Lowest Common Multiple of 831,866,677,784

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 866 x 677 x 784 = 381965068128

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

866 : 1, 2, 433, 866

677 : 1, 677

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,866,677,784, is 1.

Now, the common factors can be found like this.

831:3x 277

866:2x 433

677:677

784:2x 2x 2x 2x 7x 7

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 = 381965068128/(1x2)

LCM = 381965068128/2

LCM = 190982534064

Thus, we can understand that the LCM of 831,866,677,784 is 190982534064.
