Given numbers are 789, 660, 875, 729
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 660) = 173580
GCD(789, 660) = ( 789 x 660 ) / 173580
= 789 / 660
= 789
Step2:
LCM(3, 875) = 2625
GCD(3, 875) = ( 3 x 875 ) / 2625
= 3 / 875
= 3
Step3:
LCM(1, 729) = 729
GCD(1, 729) = ( 1 x 729 ) / 729
= 1 / 729
= 1
So, Greatest Common Divisor of 789, 660, 875, 729 is 1
