The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 871 are 13 x 67

Prime factors of 890 are 2 x 5 x 89

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

Given numbers are 945, 680, 871, 890

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

Apply this formula for all numbers.

Step1:

LCM(945, 680) = 128520

GCD(945, 680) = ( 945 x 680 ) / 128520

= 945 / 680

= 945

Step2:

LCM(5, 871) = 4355

GCD(5, 871) = ( 5 x 871 ) / 4355

= 5 / 871

= 5

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 945, 680, 871, 890 is 1
