Given numbers are 978, 475, 966, 305

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 475 are 5 x 5 x 19

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 305 are 5 x 61

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 978, 475, 966, 305

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

Apply this formula for all numbers.

Step1:

LCM(978, 475) = 464550

GCD(978, 475) = ( 978 x 475 ) / 464550

= 978 / 475

= 978

Step2:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

Step3:

LCM(1, 305) = 305

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

= 1 / 305

= 1

So, Greatest Common Divisor of 978, 475, 966, 305 is 1
