GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 559) = 29068
GCD(676, 559) = ( 676 x 559 ) / 29068
= 676 / 559
= 676
Step2:
LCM(13, 428) = 5564
GCD(13, 428) = ( 13 x 428 ) / 5564
= 13 / 428
= 13
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 676, 559, 428, 556 is 1
