GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 393) = 104538
GCD(798, 393) = ( 798 x 393 ) / 104538
= 798 / 393
= 798
Step2:
LCM(3, 563) = 1689
GCD(3, 563) = ( 3 x 563 ) / 1689
= 3 / 563
= 3
Step3:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
So, Greatest Common Divisor of 798, 393, 563, 783 is 1
