Given numbers are 865, 345, 503, 231

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 345 are 3 x 5 x 23

Prime factors of 503 are 503

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 865, 345, 503, 231

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

Apply this formula for all numbers.

Step1:

LCM(865, 345) = 59685

GCD(865, 345) = ( 865 x 345 ) / 59685

= 865 / 345

= 865

Step2:

LCM(5, 503) = 2515

GCD(5, 503) = ( 5 x 503 ) / 2515

= 5 / 503

= 5

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 865, 345, 503, 231 is 1
