Calculate the LCM of 662,771,722,856

Given numbers are 662,771,722,856

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

The LCM of 662,771,722,856 is 78861192216.

Find LCM of 662,771,722,856 with Prime Factorization


2 662, 771, 722, 856
331, 771, 361, 428

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

2 x 331 x 771 x 361 x 428 = 78861192216

Therefore, the lowest common multiple of 662,771,722,856 is 78861192216.

LCM Formula to Find Lowest Common Multiple of 662,771,722,856

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.

662 x 771 x 722 x 856 = 315444768864

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.

662 : 1, 2, 331, 662

771 : 1, 3, 257, 771

722 : 1, 2, 19, 38, 361, 722

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,771,722,856, is 1.

Now, the common factors can be found like this.

662:2x 331

771:3x 257

722:2x 19x 19

856:2x 2x 2x 107

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 = 315444768864/(1x4)

LCM = 315444768864/4

LCM = 78861192216

Thus, we can understand that the LCM of 662,771,722,856 is 78861192216.
