Given numbers are 393, 779, 285, 161

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(393, 779) = 306147

GCD(393, 779) = ( 393 x 779 ) / 306147

= 393 / 779

= 393

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 393, 779, 285, 161 is 1
