Given numbers are 225, 408, 277, 756

The list of prime factors of all numbers are

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

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 277 are 277

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 225, 408, 277, 756

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

Apply this formula for all numbers.

Step1:

LCM(225, 408) = 30600

GCD(225, 408) = ( 225 x 408 ) / 30600

= 225 / 408

= 225

Step2:

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

= 3 / 277

= 3

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 225, 408, 277, 756 is 1
