Given numbers are 197,985,581,985

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

The LCM of 197,985,581,985 is 572285.

Find LCM of 197,985,581,985 with Prime Factorization

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

5 x 197 x 1 x 1 x 581 x 1 = 572285

Therefore, the lowest common multiple of 197,985,581,985 is 572285.

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 985 x 581 x 985 = 111049042825

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

985 : 1, 5, 197, 985

581 : 1, 7, 83, 581

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,985,581,985, is 1.

Now, the common factors can be found like this.

197:197

985:5x 197

581:7x 83

985:5x 197

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

5x 197x 197 = 194045

Therefore, the value for common factors is 194045.

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 = 111049042825/(1x194045)

LCM = 111049042825/194045

LCM = 572285

Thus, we can understand that the LCM of 197,985,581,985 is 572285.
