Given numbers are 111, 442, 395, 721

The list of prime factors of all numbers are

Prime factors of 111 are 3 x 37

Prime factors of 442 are 2 x 13 x 17

Prime factors of 395 are 5 x 79

Prime factors of 721 are 7 x 103

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

Given numbers are 111, 442, 395, 721

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

Apply this formula for all numbers.

Step1:

LCM(111, 442) = 49062

GCD(111, 442) = ( 111 x 442 ) / 49062

= 111 / 442

= 111

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 111, 442, 395, 721 is 1
