Given numbers are 391, 930, 425, 305

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

Apply this formula for all numbers.

Step1:

LCM(391, 930) = 363630

GCD(391, 930) = ( 391 x 930 ) / 363630

= 391 / 930

= 391

Step2:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 391, 930, 425, 305 is 1
