Calculate the LCM of 197,985,981,617

Given numbers are 197,985,981,617

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

The LCM of 197,985,981,617 is 596197845.

Find LCM of 197,985,981,617 with Prime Factorization


197 197, 985, 981, 617
1, 5, 981, 617

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

197 x 1 x 5 x 981 x 617 = 596197845

Therefore, the lowest common multiple of 197,985,981,617 is 596197845.

LCM Formula to Find Lowest Common Multiple of 197,985,981,617

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 981 x 617 = 117450975465

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

981 : 1, 3, 9, 109, 327, 981

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,985,981,617, is 1.

Now, the common factors can be found like this.

197:197

985:5x 197

981:3x 3x 109

617:617

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 = 117450975465/(1x197)

LCM = 117450975465/197

LCM = 596197845

Thus, we can understand that the LCM of 197,985,981,617 is 596197845.
