Given numbers are 721, 114, 687, 447

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 114 are 2 x 3 x 19

Prime factors of 687 are 3 x 229

Prime factors of 447 are 3 x 149

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

Given numbers are 721, 114, 687, 447

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

Apply this formula for all numbers.

Step1:

LCM(721, 114) = 82194

GCD(721, 114) = ( 721 x 114 ) / 82194

= 721 / 114

= 721

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 721, 114, 687, 447 is 1
