Given numbers are 789, 284, 287, 682
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 284) = 224076
GCD(789, 284) = ( 789 x 284 ) / 224076
= 789 / 284
= 789
Step2:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
Step3:
LCM(1, 682) = 682
GCD(1, 682) = ( 1 x 682 ) / 682
= 1 / 682
= 1
So, Greatest Common Divisor of 789, 284, 287, 682 is 1
