Given numbers are 309, 285, 781, 941

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

Apply this formula for all numbers.

Step1:

LCM(309, 285) = 29355

GCD(309, 285) = ( 309 x 285 ) / 29355

= 309 / 285

= 309

Step2:

LCM(3, 781) = 2343

GCD(3, 781) = ( 3 x 781 ) / 2343

= 3 / 781

= 3

Step3:

LCM(1, 941) = 941

GCD(1, 941) = ( 1 x 941 ) / 941

= 1 / 941

= 1

So, Greatest Common Divisor of 309, 285, 781, 941 is 1
