GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 978) = 107580
GCD(660, 978) = ( 660 x 978 ) / 107580
= 660 / 978
= 660
Step2:
LCM(6, 750) = 750
GCD(6, 750) = ( 6 x 750 ) / 750
= 6 / 750
= 6
Step3:
LCM(6, 789) = 1578
GCD(6, 789) = ( 6 x 789 ) / 1578
= 6 / 789
= 6
So, Greatest Common Divisor of 660, 978, 750, 789 is 3
