Given numbers are 815,515,910

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

The LCM of 815,515,910 is 15277990.

Find LCM of 815,515,910 with Prime Factorization

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

5 x 163 x 103 x 182 = 15277990

Therefore, the lowest common multiple of 815,515,910 is 15277990.

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.

815 x 515 x 910 = 381949750

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.

815 : 1, 5, 163, 815

515 : 1, 5, 103, 515

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,515,910, is 5.

Now, the common factors can be found like this.

815:5x 163

515:5x 103

910:2x 5x 7x 13

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

5 = 5

Therefore, the value for common factors is 5.

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 = 381949750/(5x5)

LCM = 381949750/25

LCM = 15277990

Thus, we can understand that the LCM of 815,515,910 is 15277990.
