GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 559) = 362791
GCD(649, 559) = ( 649 x 559 ) / 362791
= 649 / 559
= 649
Step2:
LCM(1, 927) = 927
GCD(1, 927) = ( 1 x 927 ) / 927
= 1 / 927
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 649, 559, 927, 420 is 1
