GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 823) = 716833
GCD(871, 823) = ( 871 x 823 ) / 716833
= 871 / 823
= 871
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 677) = 677
GCD(1, 677) = ( 1 x 677 ) / 677
= 1 / 677
= 1
So, Greatest Common Divisor of 871, 823, 981, 677 is 1
