GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 930) = 73470
GCD(395, 930) = ( 395 x 930 ) / 73470
= 395 / 930
= 395
Step2:
LCM(5, 637) = 3185
GCD(5, 637) = ( 5 x 637 ) / 3185
= 5 / 637
= 5
Step3:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
So, Greatest Common Divisor of 395, 930, 637, 817 is 1
