Given numbers are 231, 170, 721

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 170 are 2 x 5 x 17

Prime factors of 721 are 7 x 103

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

Given numbers are 231, 170, 721

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

Apply this formula for all numbers.

Step1:

LCM(231, 170) = 39270

GCD(231, 170) = ( 231 x 170 ) / 39270

= 231 / 170

= 231

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 231, 170, 721 is 1
