GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 819) = 107289
GCD(393, 819) = ( 393 x 819 ) / 107289
= 393 / 819
= 393
Step2:
LCM(3, 742) = 2226
GCD(3, 742) = ( 3 x 742 ) / 2226
= 3 / 742
= 3
Step3:
LCM(1, 263) = 263
GCD(1, 263) = ( 1 x 263 ) / 263
= 1 / 263
= 1
So, Greatest Common Divisor of 393, 819, 742, 263 is 1
