Given numbers are 945, 291, 656, 310
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 291) = 91665
GCD(945, 291) = ( 945 x 291 ) / 91665
= 945 / 291
= 945
Step2:
LCM(3, 656) = 1968
GCD(3, 656) = ( 3 x 656 ) / 1968
= 3 / 656
= 3
Step3:
LCM(1, 310) = 310
GCD(1, 310) = ( 1 x 310 ) / 310
= 1 / 310
= 1
So, Greatest Common Divisor of 945, 291, 656, 310 is 1
