Given numbers are 231, 462, 905, 121

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 905 are 5 x 181

Prime factors of 121 are 11 x 11

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

Given numbers are 231, 462, 905, 121

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

Apply this formula for all numbers.

Step1:

LCM(231, 462) = 462

GCD(231, 462) = ( 231 x 462 ) / 462

= 231 / 462

= 231

Step2:

LCM(231, 905) = 209055

GCD(231, 905) = ( 231 x 905 ) / 209055

= 231 / 905

= 231

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 231, 462, 905, 121 is 1
