Given numbers are 258, 798, 298, 691

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

Apply this formula for all numbers.

Step1:

LCM(258, 798) = 34314

GCD(258, 798) = ( 258 x 798 ) / 34314

= 258 / 798

= 258

Step2:

LCM(6, 298) = 894

GCD(6, 298) = ( 6 x 298 ) / 894

= 6 / 298

= 6

Step3:

LCM(2, 691) = 1382

GCD(2, 691) = ( 2 x 691 ) / 1382

= 2 / 691

= 2

So, Greatest Common Divisor of 258, 798, 298, 691 is 1
