Given numbers are 721, 308, 228, 123

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 308 are 2 x 2 x 7 x 11

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

Prime factors of 123 are 3 x 41

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

Given numbers are 721, 308, 228, 123

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

Apply this formula for all numbers.

Step1:

LCM(721, 308) = 31724

GCD(721, 308) = ( 721 x 308 ) / 31724

= 721 / 308

= 721

Step2:

LCM(7, 228) = 1596

GCD(7, 228) = ( 7 x 228 ) / 1596

= 7 / 228

= 7

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 721, 308, 228, 123 is 1
