Calculate the LCM of 813,318,257,660

Given numbers are 813,318,257,660

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

The LCM of 813,318,257,660 is 2436252060.

Find LCM of 813,318,257,660 with Prime Factorization


2 813, 318, 257, 660
3 813, 159, 257, 330
271, 53, 257, 110

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

2 x 3 x 271 x 53 x 257 x 110 = 2436252060

Therefore, the lowest common multiple of 813,318,257,660 is 2436252060.

LCM Formula to Find Lowest Common Multiple of 813,318,257,660

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.

813 x 318 x 257 x 660 = 43852537080

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.

813 : 1, 3, 271, 813

318 : 1, 2, 3, 6, 53, 106, 159, 318

257 : 1, 257

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,318,257,660, is 1.

Now, the common factors can be found like this.

813:3x 271

318:2x 3x 53

257:257

660:2x 2x 3x 5x 11

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 43852537080/(1x18)

LCM = 43852537080/18

LCM = 2436252060

Thus, we can understand that the LCM of 813,318,257,660 is 2436252060.
