Given numbers are 420, 943, 174, 421

The list of prime factors of all numbers are

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

Prime factors of 943 are 23 x 41

Prime factors of 174 are 2 x 3 x 29

Prime factors of 421 are 421

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

Given numbers are 420, 943, 174, 421

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

Apply this formula for all numbers.

Step1:

LCM(420, 943) = 396060

GCD(420, 943) = ( 420 x 943 ) / 396060

= 420 / 943

= 420

Step2:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 420, 943, 174, 421 is 1
