Given numbers are 225, 780, 417, 664

The list of prime factors of all numbers are

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 417 are 3 x 139

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 225, 780, 417, 664

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

Apply this formula for all numbers.

Step1:

LCM(225, 780) = 11700

GCD(225, 780) = ( 225 x 780 ) / 11700

= 225 / 780

= 225

Step2:

LCM(15, 417) = 2085

GCD(15, 417) = ( 15 x 417 ) / 2085

= 15 / 417

= 15

Step3:

LCM(3, 664) = 1992

GCD(3, 664) = ( 3 x 664 ) / 1992

= 3 / 664

= 3

So, Greatest Common Divisor of 225, 780, 417, 664 is 1
