Given numbers are 439,442,478,171

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

The LCM of 439,442,478,171 is 7930139022.

Find LCM of 439,442,478,171 with Prime Factorization

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

2 x 439 x 221 x 239 x 171 = 7930139022

Therefore, the lowest common multiple of 439,442,478,171 is 7930139022.

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.

439 x 442 x 478 x 171 = 15860278044

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.

439 : 1, 439

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

478 : 1, 2, 239, 478

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,442,478,171, is 1.

Now, the common factors can be found like this.

439:439

442:2x 13x 17

478:2x 239

171:3x 3x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 15860278044/(1x2)

LCM = 15860278044/2

LCM = 7930139022

Thus, we can understand that the LCM of 439,442,478,171 is 7930139022.
