The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 423 are 3 x 3 x 47

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 871, 980, 423, 648

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

Apply this formula for all numbers.

Step1:

LCM(871, 980) = 853580

GCD(871, 980) = ( 871 x 980 ) / 853580

= 871 / 980

= 871

Step2:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 871, 980, 423, 648 is 1
