Given numbers are 172, 161, 405, 696

The list of prime factors of all numbers are

Prime factors of 172 are 2 x 2 x 43

Prime factors of 161 are 7 x 23

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

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

Given numbers are 172, 161, 405, 696

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

Apply this formula for all numbers.

Step1:

LCM(172, 161) = 27692

GCD(172, 161) = ( 172 x 161 ) / 27692

= 172 / 161

= 172

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

So, Greatest Common Divisor of 172, 161, 405, 696 is 1
