Given numbers are 721, 422, 168, 110

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 422 are 2 x 211

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 110 are 2 x 5 x 11

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

Given numbers are 721, 422, 168, 110

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

Apply this formula for all numbers.

Step1:

LCM(721, 422) = 304262

GCD(721, 422) = ( 721 x 422 ) / 304262

= 721 / 422

= 721

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 110) = 110

GCD(1, 110) = ( 1 x 110 ) / 110

= 1 / 110

= 1

So, Greatest Common Divisor of 721, 422, 168, 110 is 1
