Given numbers are 771, 843, 168, 169

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

Apply this formula for all numbers.

Step1:

LCM(771, 843) = 216651

GCD(771, 843) = ( 771 x 843 ) / 216651

= 771 / 843

= 771

Step2:

LCM(3, 168) = 168

GCD(3, 168) = ( 3 x 168 ) / 168

= 3 / 168

= 3

Step3:

LCM(3, 169) = 507

GCD(3, 169) = ( 3 x 169 ) / 507

= 3 / 169

= 3

So, Greatest Common Divisor of 771, 843, 168, 169 is 1
