GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 789) = 226443
GCD(287, 789) = ( 287 x 789 ) / 226443
= 287 / 789
= 287
Step2:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
Step3:
LCM(1, 741) = 741
GCD(1, 741) = ( 1 x 741 ) / 741
= 1 / 741
= 1
So, Greatest Common Divisor of 287, 789, 991, 741 is 1
