GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 394) = 124898
GCD(634, 394) = ( 634 x 394 ) / 124898
= 634 / 394
= 634
Step2:
LCM(2, 504) = 504
GCD(2, 504) = ( 2 x 504 ) / 504
= 2 / 504
= 2
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 634, 394, 504, 620 is 2
