The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 305 are 5 x 61

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 454, 305, 688, 872

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

Apply this formula for all numbers.

Step1:

LCM(454, 305) = 138470

GCD(454, 305) = ( 454 x 305 ) / 138470

= 454 / 305

= 454

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 454, 305, 688, 872 is 1
