Given numbers are 668,205,123,197

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

The LCM of 668,205,123,197 is 80931540.

Find LCM of 668,205,123,197 with Prime Factorization

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

41 x 668 x 5 x 3 x 197 = 80931540

Therefore, the lowest common multiple of 668,205,123,197 is 80931540.

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.

668 x 205 x 123 x 197 = 3318193140

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.

668 : 1, 2, 4, 167, 334, 668

205 : 1, 5, 41, 205

123 : 1, 3, 41, 123

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,205,123,197, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

205:5x 41

123:3x 41

197:197

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

41 = 41

Therefore, the value for common factors is 41.

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 = 3318193140/(1x41)

LCM = 3318193140/41

LCM = 80931540

Thus, we can understand that the LCM of 668,205,123,197 is 80931540.
