GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 198) = 33462
GCD(169, 198) = ( 169 x 198 ) / 33462
= 169 / 198
= 169
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 169, 198, 644, 611 is 1
