Given numbers are 170, 676, 386, 449

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 386 are 2 x 193

Prime factors of 449 are 449

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

Given numbers are 170, 676, 386, 449

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

Apply this formula for all numbers.

Step1:

LCM(170, 676) = 57460

GCD(170, 676) = ( 170 x 676 ) / 57460

= 170 / 676

= 170

Step2:

LCM(2, 386) = 386

GCD(2, 386) = ( 2 x 386 ) / 386

= 2 / 386

= 2

Step3:

LCM(2, 449) = 898

GCD(2, 449) = ( 2 x 449 ) / 898

= 2 / 449

= 2

So, Greatest Common Divisor of 170, 676, 386, 449 is 1
