Given numbers are 515,782,731,404

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

The LCM of 515,782,731,404 is 3498112780.

Find LCM of 515,782,731,404 with Prime Factorization

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

2 x 17 x 515 x 23 x 43 x 202 = 3498112780

Therefore, the lowest common multiple of 515,782,731,404 is 3498112780.

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.

515 x 782 x 731 x 404 = 118935834520

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.

515 : 1, 5, 103, 515

782 : 1, 2, 17, 23, 34, 46, 391, 782

731 : 1, 17, 43, 731

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,782,731,404, is 1.

Now, the common factors can be found like this.

515:5x 103

782:2x 17x 23

731:17x 43

404:2x 2x 101

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 118935834520/(1x34)

LCM = 118935834520/34

LCM = 3498112780

Thus, we can understand that the LCM of 515,782,731,404 is 3498112780.
