GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(769, 620) = 476780
GCD(769, 620) = ( 769 x 620 ) / 476780
= 769 / 620
= 769
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 769, 620, 197, 320 is 1
