The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 955 are 5 x 191

Prime factors of 987 are 3 x 7 x 47

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 285, 955, 987, 305

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

Apply this formula for all numbers.

Step1:

LCM(285, 955) = 54435

GCD(285, 955) = ( 285 x 955 ) / 54435

= 285 / 955

= 285

Step2:

LCM(5, 987) = 4935

GCD(5, 987) = ( 5 x 987 ) / 4935

= 5 / 987

= 5

Step3:

LCM(1, 305) = 305

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

= 1 / 305

= 1

So, Greatest Common Divisor of 285, 955, 987, 305 is 1
