The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 284 are 2 x 2 x 71

Prime factors of 745 are 5 x 149

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

Given numbers are 721, 297, 284, 745

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

Apply this formula for all numbers.

Step1:

LCM(721, 297) = 214137

GCD(721, 297) = ( 721 x 297 ) / 214137

= 721 / 297

= 721

Step2:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 721, 297, 284, 745 is 1
