Given numbers are 198,591,338,681

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

The LCM of 198,591,338,681 is 1496387178.

Find LCM of 198,591,338,681 with Prime Factorization

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

2 x 3 x 33 x 197 x 169 x 227 = 1496387178

Therefore, the lowest common multiple of 198,591,338,681 is 1496387178.

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.

198 x 591 x 338 x 681 = 26934969204

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.

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

591 : 1, 3, 197, 591

338 : 1, 2, 13, 26, 169, 338

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,591,338,681, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

591:3x 197

338:2x 13x 13

681:3x 227

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 = 26934969204/(1x18)

LCM = 26934969204/18

LCM = 1496387178

Thus, we can understand that the LCM of 198,591,338,681 is 1496387178.
