Given numbers are 327,286,617,638

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

The LCM of 327,286,617,638 is 1673389146.

Find LCM of 327,286,617,638 with Prime Factorization

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

2 x 11 x 327 x 13 x 617 x 29 = 1673389146

Therefore, the lowest common multiple of 327,286,617,638 is 1673389146.

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.

327 x 286 x 617 x 638 = 36814561212

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.

327 : 1, 3, 109, 327

286 : 1, 2, 11, 13, 22, 26, 143, 286

617 : 1, 617

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,286,617,638, is 1.

Now, the common factors can be found like this.

327:3x 109

286:2x 11x 13

617:617

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 36814561212/(1x22)

LCM = 36814561212/22

LCM = 1673389146

Thus, we can understand that the LCM of 327,286,617,638 is 1673389146.
