Given numbers are 231, 857, 165, 415

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 857 are 857

Prime factors of 165 are 3 x 5 x 11

Prime factors of 415 are 5 x 83

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

Given numbers are 231, 857, 165, 415

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

Apply this formula for all numbers.

Step1:

LCM(231, 857) = 197967

GCD(231, 857) = ( 231 x 857 ) / 197967

= 231 / 857

= 231

Step2:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 231, 857, 165, 415 is 1
