Given numbers are 401, 170, 191, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 170) = 68170
GCD(401, 170) = ( 401 x 170 ) / 68170
= 401 / 170
= 401
Step2:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
Step3:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
So, Greatest Common Divisor of 401, 170, 191, 775 is 1
