Given numbers are 259, 561, 691, 394

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

Apply this formula for all numbers.

Step1:

LCM(259, 561) = 145299

GCD(259, 561) = ( 259 x 561 ) / 145299

= 259 / 561

= 259

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 259, 561, 691, 394 is 1
