Given numbers are 221, 342, 172

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 221, 342, 172

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

Apply this formula for all numbers.

Step1:

LCM(221, 342) = 75582

GCD(221, 342) = ( 221 x 342 ) / 75582

= 221 / 342

= 221

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 221, 342, 172 is 1
