Given numbers are 813,138,281,460

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

The LCM of 813,138,281,460 is 105088380.

Find LCM of 813,138,281,460 with Prime Factorization

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

2 x 3 x 23 x 271 x 1 x 281 x 10 = 105088380

Therefore, the lowest common multiple of 813,138,281,460 is 105088380.

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 138 x 281 x 460 = 14502196440

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

281 : 1, 281

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,138,281,460, is 1.

Now, the common factors can be found like this.

813:3x 271

138:2x 3x 23

281:281

460:2x 2x 5x 23

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 23 = 138

Therefore, the value for common factors is 138.

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 = 14502196440/(1x138)

LCM = 14502196440/138

LCM = 105088380

Thus, we can understand that the LCM of 813,138,281,460 is 105088380.
