Calculate the LCM of 481,478,256,538

Given numbers are 481,478,256,538

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

The LCM of 481,478,256,538 is 7916536576.

Find LCM of 481,478,256,538 with Prime Factorization


2 481, 478, 256, 538
481, 239, 128, 269

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

2 x 481 x 239 x 128 x 269 = 7916536576

Therefore, the lowest common multiple of 481,478,256,538 is 7916536576.

LCM Formula to Find Lowest Common Multiple of 481,478,256,538

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.

481 x 478 x 256 x 538 = 31666146304

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.

481 : 1, 13, 37, 481

478 : 1, 2, 239, 478

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

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,478,256,538, is 1.

Now, the common factors can be found like this.

481:13x 37

478:2x 239

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

538:2x 269

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 31666146304/(1x4)

LCM = 31666146304/4

LCM = 7916536576

Thus, we can understand that the LCM of 481,478,256,538 is 7916536576.
