Calculate the LCM of 418,105,423,256

Given numbers are 418,105,423,256

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

The LCM of 418,105,423,256 is 792126720.

Find LCM of 418,105,423,256 with Prime Factorization


2 418, 105, 423, 256
3 209, 105, 423, 128
209, 35, 141, 128

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

2 x 3 x 209 x 35 x 141 x 128 = 792126720

Therefore, the lowest common multiple of 418,105,423,256 is 792126720.

LCM Formula to Find Lowest Common Multiple of 418,105,423,256

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.

418 x 105 x 423 x 256 = 4752760320

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

105 : 1, 3, 5, 7, 15, 21, 35, 105

423 : 1, 3, 9, 47, 141, 423

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,105,423,256, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

105:3x 5x 7

423:3x 3x 47

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

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 4752760320/(1x6)

LCM = 4752760320/6

LCM = 792126720

Thus, we can understand that the LCM of 418,105,423,256 is 792126720.
