The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

Prime factors of 531 are 3 x 3 x 59

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

Prime factors of 254 are 2 x 127

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

Given numbers are 485, 531, 688, 254

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

Apply this formula for all numbers.

Step1:

LCM(485, 531) = 257535

GCD(485, 531) = ( 485 x 531 ) / 257535

= 485 / 531

= 485

Step2:

LCM(1, 688) = 688

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

= 1 / 688

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 485, 531, 688, 254 is 1
