Given numbers are 228, 420, 459, 755

The list of prime factors of all numbers are

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 459 are 3 x 3 x 3 x 17

Prime factors of 755 are 5 x 151

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

Given numbers are 228, 420, 459, 755

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

Apply this formula for all numbers.

Step1:

LCM(228, 420) = 7980

GCD(228, 420) = ( 228 x 420 ) / 7980

= 228 / 420

= 228

Step2:

LCM(12, 459) = 1836

GCD(12, 459) = ( 12 x 459 ) / 1836

= 12 / 459

= 12

Step3:

LCM(3, 755) = 2265

GCD(3, 755) = ( 3 x 755 ) / 2265

= 3 / 755

= 3

So, Greatest Common Divisor of 228, 420, 459, 755 is 1
