Given numbers are 789, 167, 787, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 167) = 131763
GCD(789, 167) = ( 789 x 167 ) / 131763
= 789 / 167
= 789
Step2:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
Step3:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
So, Greatest Common Divisor of 789, 167, 787, 345 is 1
