Given numbers are 423, 421, 778, 228

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 421 are 421

Prime factors of 778 are 2 x 389

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

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

Given numbers are 423, 421, 778, 228

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

Apply this formula for all numbers.

Step1:

LCM(423, 421) = 178083

GCD(423, 421) = ( 423 x 421 ) / 178083

= 423 / 421

= 423

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 423, 421, 778, 228 is 1
