Given numbers are 639,165,796,393

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

The LCM of 639,165,796,393 is 3664780020.

Find LCM of 639,165,796,393 with Prime Factorization

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

3 x 213 x 55 x 796 x 131 = 3664780020

Therefore, the lowest common multiple of 639,165,796,393 is 3664780020.

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 165 x 796 x 393 = 32983020180

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

165 : 1, 3, 5, 11, 15, 33, 55, 165

796 : 1, 2, 4, 199, 398, 796

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,165,796,393, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

165:3x 5x 11

796:2x 2x 199

393:3x 131

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 32983020180/(1x9)

LCM = 32983020180/9

LCM = 3664780020

Thus, we can understand that the LCM of 639,165,796,393 is 3664780020.
