Given numbers are 111, 420, 173, 943

The list of prime factors of all numbers are

Prime factors of 111 are 3 x 37

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

Prime factors of 173 are 173

Prime factors of 943 are 23 x 41

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

Given numbers are 111, 420, 173, 943

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

Apply this formula for all numbers.

Step1:

LCM(111, 420) = 15540

GCD(111, 420) = ( 111 x 420 ) / 15540

= 111 / 420

= 111

Step2:

LCM(3, 173) = 519

GCD(3, 173) = ( 3 x 173 ) / 519

= 3 / 173

= 3

Step3:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

So, Greatest Common Divisor of 111, 420, 173, 943 is 1
