Given numbers are 403, 745, 420, 238

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 745 are 5 x 149

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

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 403, 745, 420, 238

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

Apply this formula for all numbers.

Step1:

LCM(403, 745) = 300235

GCD(403, 745) = ( 403 x 745 ) / 300235

= 403 / 745

= 403

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 403, 745, 420, 238 is 1
