Given numbers are 665, 816, 509, 225

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 509 are 509

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 665, 816, 509, 225

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

Apply this formula for all numbers.

Step1:

LCM(665, 816) = 542640

GCD(665, 816) = ( 665 x 816 ) / 542640

= 665 / 816

= 665

Step2:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 665, 816, 509, 225 is 1
