Calculate the LCM of 681,271,137,662,286

Given numbers are 681,271,137,662,286

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

The LCM of 681,271,137,662,286 is 2393486580342.

Find LCM of 681,271,137,662,286 with Prime Factorization


2 681, 271, 137, 662, 286
681, 271, 137, 331, 143

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

2 x 681 x 271 x 137 x 331 x 143 = 2393486580342

Therefore, the lowest common multiple of 681,271,137,662,286 is 2393486580342.

LCM Formula to Find Lowest Common Multiple of 681,271,137,662,286

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.

681 x 271 x 137 x 662 x 286 = 4786973160684

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.

681 : 1, 3, 227, 681

271 : 1, 271

137 : 1, 137

662 : 1, 2, 331, 662

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,271,137,662,286, is 1.

Now, the common factors can be found like this.

681:3x 227

271:271

137:137

662:2x 331

286:2x 11x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 4786973160684/(1x2)

LCM = 4786973160684/2

LCM = 2393486580342

Thus, we can understand that the LCM of 681,271,137,662,286 is 2393486580342.
