Greatest Common Divisior

We found the divisors of 50, 21, 85 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 50, 21, 85 is 1.

Therefore, GCD of numbers 50, 21, 85 is 1

Given Input Data is 50, 21, 85

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

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 21 is 3 x 7

Prime Factorization of 85 is 5 x 17

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(50, 21) = 1050

GCD(50, 21) = ( 50 x 21 ) / 1050

GCD(50, 21) = 1050 / 1050

GCD(50, 21) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

GCD of 50, 21, 85 is 1
