Given numbers are 305, 489, 980, 595

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

Apply this formula for all numbers.

Step1:

LCM(305, 489) = 149145

GCD(305, 489) = ( 305 x 489 ) / 149145

= 305 / 489

= 305

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 595) = 595

GCD(1, 595) = ( 1 x 595 ) / 595

= 1 / 595

= 1

So, Greatest Common Divisor of 305, 489, 980, 595 is 1
