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

Apply this formula for all numbers.

Step1:

LCM(771, 309) = 79413

GCD(771, 309) = ( 771 x 309 ) / 79413

= 771 / 309

= 771

Step2:

LCM(3, 567) = 567

GCD(3, 567) = ( 3 x 567 ) / 567

= 3 / 567

= 3

Step3:

LCM(3, 195) = 195

GCD(3, 195) = ( 3 x 195 ) / 195

= 3 / 195

= 3

So, Greatest Common Divisor of 771, 309, 567, 195 is 3
