Given numbers are 561, 231, 831, 331

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 231 are 3 x 7 x 11

Prime factors of 831 are 3 x 277

Prime factors of 331 are 331

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

Given numbers are 561, 231, 831, 331

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

Apply this formula for all numbers.

Step1:

LCM(561, 231) = 3927

GCD(561, 231) = ( 561 x 231 ) / 3927

= 561 / 231

= 561

Step2:

LCM(33, 831) = 9141

GCD(33, 831) = ( 33 x 831 ) / 9141

= 33 / 831

= 33

Step3:

LCM(3, 331) = 993

GCD(3, 331) = ( 3 x 331 ) / 993

= 3 / 331

= 3

So, Greatest Common Divisor of 561, 231, 831, 331 is 1
