We found the divisors of 68, 53, 82, 28 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 68, 53, 82, 28 is 1.

Therefore, GCD of numbers 68, 53, 82, 28 is 1

Given Input Data is 68, 53, 82, 28

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

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 53 is 53

Prime Factorization of 82 is 2 x 41

Prime Factorization of 28 is 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(68, 53) = 3604

GCD(68, 53) = ( 68 x 53 ) / 3604

GCD(68, 53) = 3604 / 3604

GCD(68, 53) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 82

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

LCM(1, 82) = 82

GCD(1, 82) = ( 1 x 82 ) / 82

GCD(1, 82) = 82 / 82

GCD(1, 82) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

GCD of 68, 53, 82, 28 is 1
