GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 345) = 19320
GCD(168, 345) = ( 168 x 345 ) / 19320
= 168 / 345
= 168
Step2:
LCM(3, 808) = 2424
GCD(3, 808) = ( 3 x 808 ) / 2424
= 3 / 808
= 3
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 168, 345, 808, 580 is 1
