Given numbers are 193, 451, 309, 871
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(193, 451) = 87043
GCD(193, 451) = ( 193 x 451 ) / 87043
= 193 / 451
= 193
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
So, Greatest Common Divisor of 193, 451, 309, 871 is 1
