The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 283 are 283

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

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

Given numbers are 639, 283, 440, 792

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

Apply this formula for all numbers.

Step1:

LCM(639, 283) = 180837

GCD(639, 283) = ( 639 x 283 ) / 180837

= 639 / 283

= 639

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1

So, Greatest Common Divisor of 639, 283, 440, 792 is 1
