Greatest Common Divisior

We found the divisors of 85, 70, 82 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 85, 70, 82 is 1.

Therefore, GCD of numbers 85, 70, 82 is 1

Given Input Data is 85, 70, 82

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 85 is 5 x 17

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 82 is 2 x 41

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(85, 70) = 1190

GCD(85, 70) = ( 85 x 70 ) / 1190

GCD(85, 70) = 5950 / 1190

GCD(85, 70) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 82

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 82) = 410

GCD(5, 82) = ( 5 x 82 ) / 410

GCD(5, 82) = 410 / 410

GCD(5, 82) = 1

GCD of 85, 70, 82 is 1
