Given numbers are 871, 222, 504, 138

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 222 are 2 x 3 x 37

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 871, 222, 504, 138

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

Apply this formula for all numbers.

Step1:

LCM(871, 222) = 193362

GCD(871, 222) = ( 871 x 222 ) / 193362

= 871 / 222

= 871

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 871, 222, 504, 138 is 1
