Given numbers are 128, 198, 225

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 198 are 2 x 3 x 3 x 11

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 128, 198, 225

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

Apply this formula for all numbers.

Step1:

LCM(128, 198) = 12672

GCD(128, 198) = ( 128 x 198 ) / 12672

= 128 / 198

= 128

Step2:

LCM(2, 225) = 450

GCD(2, 225) = ( 2 x 225 ) / 450

= 2 / 225

= 2

So, Greatest Common Divisor of 128, 198, 225 is 1
