Given numbers are 871, 546, 231, 978

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 231 are 3 x 7 x 11

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 871, 546, 231, 978

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

Apply this formula for all numbers.

Step1:

LCM(871, 546) = 36582

GCD(871, 546) = ( 871 x 546 ) / 36582

= 871 / 546

= 871

Step2:

LCM(13, 231) = 3003

GCD(13, 231) = ( 13 x 231 ) / 3003

= 13 / 231

= 13

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 871, 546, 231, 978 is 1
