GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 178) = 73158
GCD(822, 178) = ( 822 x 178 ) / 73158
= 822 / 178
= 822
Step2:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
Step3:
LCM(2, 246) = 246
GCD(2, 246) = ( 2 x 246 ) / 246
= 2 / 246
= 2
So, Greatest Common Divisor of 822, 178, 556, 246 is 2
