Given numbers are 851, 771, 395, 251

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

Apply this formula for all numbers.

Step1:

LCM(851, 771) = 656121

GCD(851, 771) = ( 851 x 771 ) / 656121

= 851 / 771

= 851

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 851, 771, 395, 251 is 1
