Given numbers are 771, 720, 479, 231

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 479 are 479

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 771, 720, 479, 231

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

Apply this formula for all numbers.

Step1:

LCM(771, 720) = 185040

GCD(771, 720) = ( 771 x 720 ) / 185040

= 771 / 720

= 771

Step2:

LCM(3, 479) = 1437

GCD(3, 479) = ( 3 x 479 ) / 1437

= 3 / 479

= 3

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 771, 720, 479, 231 is 1
