GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(163, 654) = 106602
GCD(163, 654) = ( 163 x 654 ) / 106602
= 163 / 654
= 163
Step2:
LCM(1, 963) = 963
GCD(1, 963) = ( 1 x 963 ) / 963
= 1 / 963
= 1
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 163, 654, 963, 686 is 1
