Calculate the LCM of 867,878,656,939

Given numbers are 867,878,656,939

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

The LCM of 867,878,656,939 is 78150506064.

Find LCM of 867,878,656,939 with Prime Factorization


2 867, 878, 656, 939
3 867, 439, 328, 939
289, 439, 328, 313

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

2 x 3 x 289 x 439 x 328 x 313 = 78150506064

Therefore, the lowest common multiple of 867,878,656,939 is 78150506064.

LCM Formula to Find Lowest Common Multiple of 867,878,656,939

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.

867 x 878 x 656 x 939 = 468903036384

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.

867 : 1, 3, 17, 51, 289, 867

878 : 1, 2, 439, 878

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

939 : 1, 3, 313, 939

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,878,656,939, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

878:2x 439

656:2x 2x 2x 2x 41

939:3x 313

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 468903036384/(1x6)

LCM = 468903036384/6

LCM = 78150506064

Thus, we can understand that the LCM of 867,878,656,939 is 78150506064.
