GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 665) = 185535
GCD(279, 665) = ( 279 x 665 ) / 185535
= 279 / 665
= 279
Step2:
LCM(1, 866) = 866
GCD(1, 866) = ( 1 x 866 ) / 866
= 1 / 866
= 1
Step3:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
So, Greatest Common Divisor of 279, 665, 866, 225 is 1
