GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 786) = 206718
GCD(789, 786) = ( 789 x 786 ) / 206718
= 789 / 786
= 789
Step2:
LCM(3, 894) = 894
GCD(3, 894) = ( 3 x 894 ) / 894
= 3 / 894
= 3
Step3:
LCM(3, 721) = 2163
GCD(3, 721) = ( 3 x 721 ) / 2163
= 3 / 721
= 3
So, Greatest Common Divisor of 789, 786, 894, 721 is 1
