GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 126) = 10710
GCD(765, 126) = ( 765 x 126 ) / 10710
= 765 / 126
= 765
Step2:
LCM(9, 189) = 189
GCD(9, 189) = ( 9 x 189 ) / 189
= 9 / 189
= 9
Step3:
LCM(9, 189) = 189
GCD(9, 189) = ( 9 x 189 ) / 189
= 9 / 189
= 9
So, Greatest Common Divisor of 765, 126, 189, 189 is 9
