Given numbers are 765, 676, 23, 257

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

Apply this formula for all numbers.

Step1:

LCM(765, 676) = 517140

GCD(765, 676) = ( 765 x 676 ) / 517140

= 765 / 676

= 765

Step2:

LCM(1, 23) = 23

GCD(1, 23) = ( 1 x 23 ) / 23

= 1 / 23

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 765, 676, 23, 257 is 1
