Given numbers are 197,173,591,689

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

The LCM of 197,173,591,689 is 70445427.

Find LCM of 197,173,591,689 with Prime Factorization

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

197 x 1 x 173 x 3 x 689 = 70445427

Therefore, the lowest common multiple of 197,173,591,689 is 70445427.

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.

197 x 173 x 591 x 689 = 13877749119

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.

197 : 1, 197

173 : 1, 173

591 : 1, 3, 197, 591

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,173,591,689, is 1.

Now, the common factors can be found like this.

197:197

173:173

591:3x 197

689:13x 53

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

197 = 197

Therefore, the value for common factors is 197.

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 = 13877749119/(1x197)

LCM = 13877749119/197

LCM = 70445427

Thus, we can understand that the LCM of 197,173,591,689 is 70445427.
