GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 187) = 59279
GCD(317, 187) = ( 317 x 187 ) / 59279
= 317 / 187
= 317
Step2:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 317, 187, 487, 991 is 1
