The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 573 are 3 x 191

Prime factors of 138 are 2 x 3 x 23

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 815, 573, 138, 231

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

Apply this formula for all numbers.

Step1:

LCM(815, 573) = 466995

GCD(815, 573) = ( 815 x 573 ) / 466995

= 815 / 573

= 815

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 231) = 231

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

= 1 / 231

= 1

So, Greatest Common Divisor of 815, 573, 138, 231 is 1
