Calculate the LCM of 156,856,646,749

Given numbers are 156,856,646,749

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

The LCM of 156,856,646,749 is 75481224.

Find LCM of 156,856,646,749 with Prime Factorization


2 156, 856, 646, 749
2 78, 428, 323, 749
107 39, 214, 323, 749
39, 2, 323, 7

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

2 x 2 x 107 x 39 x 2 x 323 x 7 = 75481224

Therefore, the lowest common multiple of 156,856,646,749 is 75481224.

LCM Formula to Find Lowest Common Multiple of 156,856,646,749

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.

156 x 856 x 646 x 749 = 64611927744

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.

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

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

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

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,856,646,749, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

856:2x 2x 2x 107

646:2x 17x 19

749:7x 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 2x 2x 107 = 856

Therefore, the value for common factors is 856.

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 = 64611927744/(1x856)

LCM = 64611927744/856

LCM = 75481224

Thus, we can understand that the LCM of 156,856,646,749 is 75481224.
