Given numbers are 261, 177, 819, 457

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

Apply this formula for all numbers.

Step1:

LCM(261, 177) = 15399

GCD(261, 177) = ( 261 x 177 ) / 15399

= 261 / 177

= 261

Step2:

LCM(3, 819) = 819

GCD(3, 819) = ( 3 x 819 ) / 819

= 3 / 819

= 3

Step3:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

So, Greatest Common Divisor of 261, 177, 819, 457 is 1
