Given numbers are 283, 287, 792, 644

The list of prime factors of all numbers are

Prime factors of 283 are 283

Prime factors of 287 are 7 x 41

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

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 283, 287, 792, 644

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

Apply this formula for all numbers.

Step1:

LCM(283, 287) = 81221

GCD(283, 287) = ( 283 x 287 ) / 81221

= 283 / 287

= 283

Step2:

LCM(1, 792) = 792

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

= 1 / 792

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 283, 287, 792, 644 is 1
