Given numbers are 639,294,474,922,912

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

The LCM of 639,294,474,922,912 is 346655853936.

Find LCM of 639,294,474,922,912 with Prime Factorization

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

2 x 3 x 213 x 49 x 79 x 461 x 152 = 346655853936

Therefore, the lowest common multiple of 639,294,474,922,912 is 346655853936.

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 294 x 474 x 922 x 912 = 74877664450176

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

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

474 : 1, 2, 3, 6, 79, 158, 237, 474

922 : 1, 2, 461, 922

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,294,474,922,912, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

294:2x 3x 7x 7

474:2x 3x 79

922:2x 461

912:2x 2x 2x 2x 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.

2x 2x 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 74877664450176/(1x216)

LCM = 74877664450176/216

LCM = 346655853936

Thus, we can understand that the LCM of 639,294,474,922,912 is 346655853936.
