We found the divisors of 212, 203, 220, 279 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 212, 203, 220, 279 is 1.

Therefore, GCD of numbers 212, 203, 220, 279 is 1

Given Input Data is 212, 203, 220, 279

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

Prime Factorization of 212 is 2 x 2 x 53

Prime Factorization of 203 is 7 x 29

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 279 is 3 x 3 x 31

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(212, 203) = 43036

GCD(212, 203) = ( 212 x 203 ) / 43036

GCD(212, 203) = 43036 / 43036

GCD(212, 203) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 279

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

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

GCD(1, 279) = 279 / 279

GCD(1, 279) = 1

GCD of 212, 203, 220, 279 is 1
