We found the divisors of 212, 127, 20, 546 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 212, 127, 20, 546 is 1.

Therefore, GCD of numbers 212, 127, 20, 546 is 1

Given Input Data is 212, 127, 20, 546

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 127 is 127

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 546 is 2 x 3 x 7 x 13

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, 127) = 26924

GCD(212, 127) = ( 212 x 127 ) / 26924

GCD(212, 127) = 26924 / 26924

GCD(212, 127) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 546

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

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

GCD(1, 546) = 546 / 546

GCD(1, 546) = 1

GCD of 212, 127, 20, 546 is 1
