The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 206 are 2 x 103

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 326 are 2 x 163

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

Given numbers are 721, 206, 858, 326

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

Apply this formula for all numbers.

Step1:

LCM(721, 206) = 1442

GCD(721, 206) = ( 721 x 206 ) / 1442

= 721 / 206

= 721

Step2:

LCM(103, 858) = 88374

GCD(103, 858) = ( 103 x 858 ) / 88374

= 103 / 858

= 103

Step3:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

So, Greatest Common Divisor of 721, 206, 858, 326 is 1
