Given numbers are 227,442,731,391

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

The LCM of 227,442,731,391 is 99230326.

Find LCM of 227,442,731,391 with Prime Factorization

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

17 x 227 x 26 x 43 x 23 = 99230326

Therefore, the lowest common multiple of 227,442,731,391 is 99230326.

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.

227 x 442 x 731 x 391 = 28677564214

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.

227 : 1, 227

442 : 1, 2, 13, 17, 26, 34, 221, 442

731 : 1, 17, 43, 731

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,442,731,391, is 1.

Now, the common factors can be found like this.

227:227

442:2x 13x 17

731:17x 43

391:17x 23

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 28677564214/(1x289)

LCM = 28677564214/289

LCM = 99230326

Thus, we can understand that the LCM of 227,442,731,391 is 99230326.
