Given numbers are 185, 172, 285, 161

The list of prime factors of all numbers are

Prime factors of 185 are 5 x 37

Prime factors of 172 are 2 x 2 x 43

Prime factors of 285 are 3 x 5 x 19

Prime factors of 161 are 7 x 23

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

Given numbers are 185, 172, 285, 161

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

Apply this formula for all numbers.

Step1:

LCM(185, 172) = 31820

GCD(185, 172) = ( 185 x 172 ) / 31820

= 185 / 172

= 185

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 185, 172, 285, 161 is 1
