Given numbers are 855, 453, 581, 231

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 453 are 3 x 151

Prime factors of 581 are 7 x 83

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 855, 453, 581, 231

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

Apply this formula for all numbers.

Step1:

LCM(855, 453) = 129105

GCD(855, 453) = ( 855 x 453 ) / 129105

= 855 / 453

= 855

Step2:

LCM(3, 581) = 1743

GCD(3, 581) = ( 3 x 581 ) / 1743

= 3 / 581

= 3

Step3:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

So, Greatest Common Divisor of 855, 453, 581, 231 is 1
