Given numbers are 231, 490, 251, 865

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 251 are 251

Prime factors of 865 are 5 x 173

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

Given numbers are 231, 490, 251, 865

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

Apply this formula for all numbers.

Step1:

LCM(231, 490) = 16170

GCD(231, 490) = ( 231 x 490 ) / 16170

= 231 / 490

= 231

Step2:

LCM(7, 251) = 1757

GCD(7, 251) = ( 7 x 251 ) / 1757

= 7 / 251

= 7

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 231, 490, 251, 865 is 1
