GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 427) = 336903
GCD(789, 427) = ( 789 x 427 ) / 336903
= 789 / 427
= 789
Step2:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 789, 427, 979, 155 is 1
