Given numbers are 789, 723, 641, 930
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 723) = 190149
GCD(789, 723) = ( 789 x 723 ) / 190149
= 789 / 723
= 789
Step2:
LCM(3, 641) = 1923
GCD(3, 641) = ( 3 x 641 ) / 1923
= 3 / 641
= 3
Step3:
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
= 1 / 930
= 1
So, Greatest Common Divisor of 789, 723, 641, 930 is 1
