Given numbers are 417,317,639,213

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

The LCM of 417,317,639,213 is 28156257.

Find LCM of 417,317,639,213 with Prime Factorization

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

3 x 71 x 139 x 317 x 3 x 1 = 28156257

Therefore, the lowest common multiple of 417,317,639,213 is 28156257.

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.

417 x 317 x 639 x 213 = 17991848223

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.

417 : 1, 3, 139, 417

317 : 1, 317

639 : 1, 3, 9, 71, 213, 639

213 : 1, 3, 71, 213

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,317,639,213, is 1.

Now, the common factors can be found like this.

417:3x 139

317:317

639:3x 3x 71

213:3x 71

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

3x 3x 71 = 639

Therefore, the value for common factors is 639.

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 = 17991848223/(1x639)

LCM = 17991848223/639

LCM = 28156257

Thus, we can understand that the LCM of 417,317,639,213 is 28156257.
