We found the divisors of 221, 272, 771, 377 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 221, 272, 771, 377 is 1.

Therefore, GCD of numbers 221, 272, 771, 377 is 1

Given Input Data is 221, 272, 771, 377

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 272 is 2 x 2 x 2 x 2 x 17

Prime Factorization of 771 is 3 x 257

Prime Factorization of 377 is 13 x 29

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(221, 272) = 3536

GCD(221, 272) = ( 221 x 272 ) / 3536

GCD(221, 272) = 60112 / 3536

GCD(221, 272) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 771

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

LCM(17, 771) = 13107

GCD(17, 771) = ( 17 x 771 ) / 13107

GCD(17, 771) = 13107 / 13107

GCD(17, 771) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 377

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

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

GCD(1, 377) = 377 / 377

GCD(1, 377) = 1

GCD of 221, 272, 771, 377 is 1
