Calculate the LCM of 326,856,808,686

Given numbers are 326,856,808,686

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

The LCM of 326,856,808,686 is 4833668504.

Find LCM of 326,856,808,686 with Prime Factorization


2 326, 856, 808, 686
2 163, 428, 404, 343
2 163, 214, 202, 343
163, 107, 101, 343

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

2 x 2 x 2 x 163 x 107 x 101 x 343 = 4833668504

Therefore, the lowest common multiple of 326,856,808,686 is 4833668504.

LCM Formula to Find Lowest Common Multiple of 326,856,808,686

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.

326 x 856 x 808 x 686 = 154677392128

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.

326 : 1, 2, 163, 326

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

808 : 1, 2, 4, 8, 101, 202, 404, 808

686 : 1, 2, 7, 14, 49, 98, 343, 686

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,856,808,686, is 2.

Now, the common factors can be found like this.

326:2x 163

856:2x 2x 2x 107

808:2x 2x 2x 101

686:2x 7x 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.

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 154677392128/(2x16)

LCM = 154677392128/32

LCM = 4833668504

Thus, we can understand that the LCM of 326,856,808,686 is 4833668504.
