Given numbers are 406, 744, 721, 228

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 721 are 7 x 103

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 406, 744, 721, 228

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

Apply this formula for all numbers.

Step1:

LCM(406, 744) = 151032

GCD(406, 744) = ( 406 x 744 ) / 151032

= 406 / 744

= 406

Step2:

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

= 2 / 721

= 2

Step3:

LCM(1, 228) = 228

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

= 1 / 228

= 1

So, Greatest Common Divisor of 406, 744, 721, 228 is 1
