The list of prime factors of all numbers are

Prime factors of 172 are 2 x 2 x 43

Prime factors of 129 are 3 x 43

Prime factors of 407 are 11 x 37

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

Given numbers are 172, 129, 407

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

Apply this formula for all numbers.

Step1:

LCM(172, 129) = 516

GCD(172, 129) = ( 172 x 129 ) / 516

= 172 / 129

= 172

Step2:

LCM(43, 407) = 17501

GCD(43, 407) = ( 43 x 407 ) / 17501

= 43 / 407

= 43

So, Greatest Common Divisor of 172, 129, 407 is 1
