Given numbers are 228, 551, 239, 420

The list of prime factors of all numbers are

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

Prime factors of 551 are 19 x 29

Prime factors of 239 are 239

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

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

Given numbers are 228, 551, 239, 420

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

Apply this formula for all numbers.

Step1:

LCM(228, 551) = 6612

GCD(228, 551) = ( 228 x 551 ) / 6612

= 228 / 551

= 228

Step2:

LCM(19, 239) = 4541

GCD(19, 239) = ( 19 x 239 ) / 4541

= 19 / 239

= 19

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 228, 551, 239, 420 is 1
