Given numbers are 722, 170, 390, 225

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 170 are 2 x 5 x 17

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 225 are 3 x 3 x 5 x 5

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

Given numbers are 722, 170, 390, 225

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

Apply this formula for all numbers.

Step1:

LCM(722, 170) = 61370

GCD(722, 170) = ( 722 x 170 ) / 61370

= 722 / 170

= 722

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 225) = 450

GCD(2, 225) = ( 2 x 225 ) / 450

= 2 / 225

= 2

So, Greatest Common Divisor of 722, 170, 390, 225 is 1
