Given numbers are 639,465,218,204,479

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

The LCM of 639,465,218,204,479 is 351644217660.

Find LCM of 639,465,218,204,479 with Prime Factorization

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

2 x 3 x 213 x 155 x 109 x 34 x 479 = 351644217660

Therefore, the lowest common multiple of 639,465,218,204,479 is 351644217660.

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.

639 x 465 x 218 x 204 x 479 = 6329595917880

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.

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

465 : 1, 3, 5, 15, 31, 93, 155, 465

218 : 1, 2, 109, 218

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,465,218,204,479, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

465:3x 5x 31

218:2x 109

204:2x 2x 3x 17

479:479

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 6329595917880/(1x18)

LCM = 6329595917880/18

LCM = 351644217660

Thus, we can understand that the LCM of 639,465,218,204,479 is 351644217660.
