Given numbers are 231, 122, 634, 427

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 122 are 2 x 61

Prime factors of 634 are 2 x 317

Prime factors of 427 are 7 x 61

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

Given numbers are 231, 122, 634, 427

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

Apply this formula for all numbers.

Step1:

LCM(231, 122) = 28182

GCD(231, 122) = ( 231 x 122 ) / 28182

= 231 / 122

= 231

Step2:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 231, 122, 634, 427 is 1
