Given numbers are 871, 643, 340, 522

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 643 are 643

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 522 are 2 x 3 x 3 x 29

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

Given numbers are 871, 643, 340, 522

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

Apply this formula for all numbers.

Step1:

LCM(871, 643) = 560053

GCD(871, 643) = ( 871 x 643 ) / 560053

= 871 / 643

= 871

Step2:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

Step3:

LCM(1, 522) = 522

GCD(1, 522) = ( 1 x 522 ) / 522

= 1 / 522

= 1

So, Greatest Common Divisor of 871, 643, 340, 522 is 1
