Given numbers are 789, 252, 309, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 252) = 66276
GCD(789, 252) = ( 789 x 252 ) / 66276
= 789 / 252
= 789
Step2:
LCM(3, 309) = 309
GCD(3, 309) = ( 3 x 309 ) / 309
= 3 / 309
= 3
Step3:
LCM(3, 166) = 498
GCD(3, 166) = ( 3 x 166 ) / 498
= 3 / 166
= 3
So, Greatest Common Divisor of 789, 252, 309, 166 is 1
