Calculate the LCM of 585,256,689,422

Given numbers are 585,256,689,422

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

The LCM of 585,256,689,422 is 1674766080.

Find LCM of 585,256,689,422 with Prime Factorization


2 585, 256, 689, 422
13 585, 128, 689, 211
45, 128, 53, 211

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

2 x 13 x 45 x 128 x 53 x 211 = 1674766080

Therefore, the lowest common multiple of 585,256,689,422 is 1674766080.

LCM Formula to Find Lowest Common Multiple of 585,256,689,422

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.

585 x 256 x 689 x 422 = 43543918080

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.

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

689 : 1, 13, 53, 689

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,256,689,422, is 1.

Now, the common factors can be found like this.

585:3x 3x 5x 13

256:2x 2x 2x 2x 2x 2x 2x 2

689:13x 53

422:2x 211

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 43543918080/(1x26)

LCM = 43543918080/26

LCM = 1674766080

Thus, we can understand that the LCM of 585,256,689,422 is 1674766080.
