Calculate the LCM of 856,338,331,278

Given numbers are 856,338,331,278

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

The LCM of 856,338,331,278 is 6655845976.

Find LCM of 856,338,331,278 with Prime Factorization


2 856, 338, 331, 278
428, 169, 331, 139

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

2 x 428 x 169 x 331 x 139 = 6655845976

Therefore, the lowest common multiple of 856,338,331,278 is 6655845976.

LCM Formula to Find Lowest Common Multiple of 856,338,331,278

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.

856 x 338 x 331 x 278 = 26623383904

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

338 : 1, 2, 13, 26, 169, 338

331 : 1, 331

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,338,331,278, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

338:2x 13x 13

331:331

278:2x 139

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 26623383904/(1x4)

LCM = 26623383904/4

LCM = 6655845976

Thus, we can understand that the LCM of 856,338,331,278 is 6655845976.
