Given numbers are 789, 735, 250, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 735) = 193305
GCD(789, 735) = ( 789 x 735 ) / 193305
= 789 / 735
= 789
Step2:
LCM(3, 250) = 750
GCD(3, 250) = ( 3 x 250 ) / 750
= 3 / 250
= 3
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 789, 735, 250, 686 is 1
