The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 561 are 3 x 11 x 17

Prime factors of 782 are 2 x 17 x 23

Prime factors of 923 are 13 x 71

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

Given numbers are 251, 561, 782, 923

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

Apply this formula for all numbers.

Step1:

LCM(251, 561) = 140811

GCD(251, 561) = ( 251 x 561 ) / 140811

= 251 / 561

= 251

Step2:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

Step3:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

So, Greatest Common Divisor of 251, 561, 782, 923 is 1
