Given numbers are 681, 810, 554, 225

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 554 are 2 x 277

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 681, 810, 554, 225

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

Apply this formula for all numbers.

Step1:

LCM(681, 810) = 183870

GCD(681, 810) = ( 681 x 810 ) / 183870

= 681 / 810

= 681

Step2:

LCM(3, 554) = 1662

GCD(3, 554) = ( 3 x 554 ) / 1662

= 3 / 554

= 3

Step3:

LCM(1, 225) = 225

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

= 1 / 225

= 1

So, Greatest Common Divisor of 681, 810, 554, 225 is 1
