The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 393 are 3 x 131

Prime factors of 795 are 3 x 5 x 53

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 745, 393, 795, 648

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

Apply this formula for all numbers.

Step1:

LCM(745, 393) = 292785

GCD(745, 393) = ( 745 x 393 ) / 292785

= 745 / 393

= 745

Step2:

LCM(1, 795) = 795

GCD(1, 795) = ( 1 x 795 ) / 795

= 1 / 795

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 745, 393, 795, 648 is 1
