Given numbers are 312, 949, 389, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 949) = 22776
GCD(312, 949) = ( 312 x 949 ) / 22776
= 312 / 949
= 312
Step2:
LCM(13, 389) = 5057
GCD(13, 389) = ( 13 x 389 ) / 5057
= 13 / 389
= 13
Step3:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
So, Greatest Common Divisor of 312, 949, 389, 422 is 1
