GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 120) = 38760
GCD(646, 120) = ( 646 x 120 ) / 38760
= 646 / 120
= 646
Step2:
LCM(2, 454) = 454
GCD(2, 454) = ( 2 x 454 ) / 454
= 2 / 454
= 2
Step3:
LCM(2, 694) = 694
GCD(2, 694) = ( 2 x 694 ) / 694
= 2 / 694
= 2
So, Greatest Common Divisor of 646, 120, 454, 694 is 2
