Given numbers are 642,273,212,831,198

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

The LCM of 642,273,212,831,198 is 56607763212.

Find LCM of 642,273,212,831,198 with Prime Factorization

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

2 x 3 x 107 x 91 x 106 x 277 x 33 = 56607763212

Therefore, the lowest common multiple of 642,273,212,831,198 is 56607763212.

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.

642 x 273 x 212 x 831 x 198 = 6113638426896

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

273 : 1, 3, 7, 13, 21, 39, 91, 273

212 : 1, 2, 4, 53, 106, 212

831 : 1, 3, 277, 831

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,273,212,831,198, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

273:3x 7x 13

212:2x 2x 53

831:3x 277

198:2x 3x 3x 11

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 6113638426896/(1x108)

LCM = 6113638426896/108

LCM = 56607763212

Thus, we can understand that the LCM of 642,273,212,831,198 is 56607763212.
