Given numbers are 305, 921, 191, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 921) = 280905
GCD(305, 921) = ( 305 x 921 ) / 280905
= 305 / 921
= 305
Step2:
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
= 1 / 191
= 1
Step3:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
So, Greatest Common Divisor of 305, 921, 191, 811 is 1
