Given numbers are 198,138,389,205

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

The LCM of 198,138,389,205 is 363158730.

Find LCM of 198,138,389,205 with Prime Factorization

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

2 x 3 x 33 x 23 x 389 x 205 = 363158730

Therefore, the lowest common multiple of 198,138,389,205 is 363158730.

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 138 x 389 x 205 = 2178952380

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

389 : 1, 389

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,138,389,205, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

138:2x 3x 23

389:389

205:5x 41

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 2178952380/(1x6)

LCM = 2178952380/6

LCM = 363158730

Thus, we can understand that the LCM of 198,138,389,205 is 363158730.
