Given numbers are 305, 639, 998, 963

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

Apply this formula for all numbers.

Step1:

LCM(305, 639) = 194895

GCD(305, 639) = ( 305 x 639 ) / 194895

= 305 / 639

= 305

Step2:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

Step3:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

So, Greatest Common Divisor of 305, 639, 998, 963 is 1
