Given numbers are 305, 905, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 905) = 55205
GCD(305, 905) = ( 305 x 905 ) / 55205
= 305 / 905
= 305
Step2:
LCM(5, 422) = 2110
GCD(5, 422) = ( 5 x 422 ) / 2110
= 5 / 422
= 5
So, Greatest Common Divisor of 305, 905, 422 is 1
