Given numbers are 393, 279, 786, 818

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

Apply this formula for all numbers.

Step1:

LCM(393, 279) = 36549

GCD(393, 279) = ( 393 x 279 ) / 36549

= 393 / 279

= 393

Step2:

LCM(3, 786) = 786

GCD(3, 786) = ( 3 x 786 ) / 786

= 3 / 786

= 3

Step3:

LCM(3, 818) = 2454

GCD(3, 818) = ( 3 x 818 ) / 2454

= 3 / 818

= 3

So, Greatest Common Divisor of 393, 279, 786, 818 is 1
