GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 193) = 156137
GCD(809, 193) = ( 809 x 193 ) / 156137
= 809 / 193
= 809
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
= 1 / 974
= 1
So, Greatest Common Divisor of 809, 193, 981, 974 is 1
