Given numbers are 309, 256, 291, 476

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

Apply this formula for all numbers.

Step1:

LCM(309, 256) = 79104

GCD(309, 256) = ( 309 x 256 ) / 79104

= 309 / 256

= 309

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

Step3:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

So, Greatest Common Divisor of 309, 256, 291, 476 is 1
