Given numbers are 721, 175, 667, 280

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 175 are 5 x 5 x 7

Prime factors of 667 are 23 x 29

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 721, 175, 667, 280

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

Apply this formula for all numbers.

Step1:

LCM(721, 175) = 18025

GCD(721, 175) = ( 721 x 175 ) / 18025

= 721 / 175

= 721

Step2:

LCM(7, 667) = 4669

GCD(7, 667) = ( 7 x 667 ) / 4669

= 7 / 667

= 7

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 721, 175, 667, 280 is 1
