Given numbers are 871, 855, 770, 575

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 575 are 5 x 5 x 23

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

Given numbers are 871, 855, 770, 575

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

Apply this formula for all numbers.

Step1:

LCM(871, 855) = 744705

GCD(871, 855) = ( 871 x 855 ) / 744705

= 871 / 855

= 871

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 575) = 575

GCD(1, 575) = ( 1 x 575 ) / 575

= 1 / 575

= 1

So, Greatest Common Divisor of 871, 855, 770, 575 is 1
