Given numbers are 225, 665, 800, 687

The list of prime factors of all numbers are

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

Prime factors of 665 are 5 x 7 x 19

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 687 are 3 x 229

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

Given numbers are 225, 665, 800, 687

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

Apply this formula for all numbers.

Step1:

LCM(225, 665) = 29925

GCD(225, 665) = ( 225 x 665 ) / 29925

= 225 / 665

= 225

Step2:

LCM(5, 800) = 800

GCD(5, 800) = ( 5 x 800 ) / 800

= 5 / 800

= 5

Step3:

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

= 5 / 687

= 5

So, Greatest Common Divisor of 225, 665, 800, 687 is 1
