Given numbers are 251, 682, 680, 170

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 682 are 2 x 11 x 31

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 251, 682, 680, 170

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

Apply this formula for all numbers.

Step1:

LCM(251, 682) = 171182

GCD(251, 682) = ( 251 x 682 ) / 171182

= 251 / 682

= 251

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 251, 682, 680, 170 is 1
