Given numbers are 205, 746, 810, 165

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 746 are 2 x 373

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 205, 746, 810, 165

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

Apply this formula for all numbers.

Step1:

LCM(205, 746) = 152930

GCD(205, 746) = ( 205 x 746 ) / 152930

= 205 / 746

= 205

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 165) = 165

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

= 1 / 165

= 1

So, Greatest Common Divisor of 205, 746, 810, 165 is 1
