Given numbers are 687,26,494,481

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

The LCM of 687,26,494,481 is 12556986.

Find LCM of 687,26,494,481 with Prime Factorization

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

2 x 13 x 687 x 1 x 19 x 37 = 12556986

Therefore, the lowest common multiple of 687,26,494,481 is 12556986.

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.

687 x 26 x 494 x 481 = 4244261268

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.

687 : 1, 3, 229, 687

26 : 1, 2, 13, 26

494 : 1, 2, 13, 19, 26, 38, 247, 494

481 : 1, 13, 37, 481

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,26,494,481, is 1.

Now, the common factors can be found like this.

687:3x 229

26:2x 13

494:2x 13x 19

481:13x 37

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

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 4244261268/(1x338)

LCM = 4244261268/338

LCM = 12556986

Thus, we can understand that the LCM of 687,26,494,481 is 12556986.
