Given numbers are 427, 443, 695, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 443) = 189161
GCD(427, 443) = ( 427 x 443 ) / 189161
= 427 / 443
= 427
Step2:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 427, 443, 695, 789 is 1
