Given numbers are 225, 816, 166, 721

The list of prime factors of all numbers are

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

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 166 are 2 x 83

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 225, 816, 166, 721

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

Apply this formula for all numbers.

Step1:

LCM(225, 816) = 61200

GCD(225, 816) = ( 225 x 816 ) / 61200

= 225 / 816

= 225

Step2:

LCM(3, 166) = 498

GCD(3, 166) = ( 3 x 166 ) / 498

= 3 / 166

= 3

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 225, 816, 166, 721 is 1
