Calculate the LCM of 855,461,418,538

Given numbers are 855,461,418,538

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

The LCM of 855,461,418,538 is 2332609290.

Find LCM of 855,461,418,538 with Prime Factorization


2 855, 461, 418, 538
19 855, 461, 209, 269
45, 461, 11, 269

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

2 x 19 x 45 x 461 x 11 x 269 = 2332609290

Therefore, the lowest common multiple of 855,461,418,538 is 2332609290.

LCM Formula to Find Lowest Common Multiple of 855,461,418,538

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.

855 x 461 x 418 x 538 = 88639153020

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

461 : 1, 461

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

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,461,418,538, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

461:461

418:2x 11x 19

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 19 = 38

Therefore, the value for common factors is 38.

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 = 88639153020/(1x38)

LCM = 88639153020/38

LCM = 2332609290

Thus, we can understand that the LCM of 855,461,418,538 is 2332609290.
