Given numbers are 231, 639, 272, 448

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 639 are 3 x 3 x 71

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 231, 639, 272, 448

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(231, 639) = 49203

GCD(231, 639) = ( 231 x 639 ) / 49203

= 231 / 639

= 231

Step2:

LCM(3, 272) = 816

GCD(3, 272) = ( 3 x 272 ) / 816

= 3 / 272

= 3

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 231, 639, 272, 448 is 1
