Given numbers are 245, 398, 991, 604

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

Apply this formula for all numbers.

Step1:

LCM(245, 398) = 97510

GCD(245, 398) = ( 245 x 398 ) / 97510

= 245 / 398

= 245

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

= 1 / 604

= 1

So, Greatest Common Divisor of 245, 398, 991, 604 is 1
