Given numbers are 915,731,731,194

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

The LCM of 915,731,731,194 is 129759810.

Find LCM of 915,731,731,194 with Prime Factorization

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

17 x 43 x 915 x 1 x 1 x 194 = 129759810

Therefore, the lowest common multiple of 915,731,731,194 is 129759810.

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 731 x 731 x 194 = 94854421110

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

731 : 1, 17, 43, 731

731 : 1, 17, 43, 731

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,731,731,194, is 1.

Now, the common factors can be found like this.

915:3x 5x 61

731:17x 43

731:17x 43

194:2x 97

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

17x 43 = 731

Therefore, the value for common factors is 731.

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 = 94854421110/(1x731)

LCM = 94854421110/731

LCM = 129759810

Thus, we can understand that the LCM of 915,731,731,194 is 129759810.
