Greatest Common Divisior

We found the divisors of 84, 52, 85, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 52, 85, 56 is 1.

Therefore, GCD of numbers 84, 52, 85, 56 is 1

Given Input Data is 84, 52, 85, 56

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 52 is 2 x 2 x 13

Prime Factorization of 85 is 5 x 17

Prime Factorization of 56 is 2 x 2 x 2 x 7

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(84, 52) = 1092

GCD(84, 52) = ( 84 x 52 ) / 1092

GCD(84, 52) = 4368 / 1092

GCD(84, 52) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 85

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

LCM(4, 85) = 340

GCD(4, 85) = ( 4 x 85 ) / 340

GCD(4, 85) = 340 / 340

GCD(4, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 84, 52, 85, 56 is 1
