Given numbers are 915,685,418,515

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

The LCM of 915,685,418,515 is 5397034170.

Find LCM of 915,685,418,515 with Prime Factorization

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

5 x 183 x 137 x 418 x 103 = 5397034170

Therefore, the lowest common multiple of 915,685,418,515 is 5397034170.

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.

915 x 685 x 418 x 515 = 134925854250

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.

915 : 1, 3, 5, 15, 61, 183, 305, 915

685 : 1, 5, 137, 685

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

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,685,418,515, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

685:5x 137

418:2x 11x 19

515:5x 103

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 134925854250/(1x25)

LCM = 134925854250/25

LCM = 5397034170

Thus, we can understand that the LCM of 915,685,418,515 is 5397034170.
