Given numbers are 342, 627, 517, 257

The list of prime factors of all numbers are

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 627 are 3 x 11 x 19

Prime factors of 517 are 11 x 47

Prime factors of 257 are 257

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

Given numbers are 342, 627, 517, 257

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

Apply this formula for all numbers.

Step1:

LCM(342, 627) = 3762

GCD(342, 627) = ( 342 x 627 ) / 3762

= 342 / 627

= 342

Step2:

LCM(57, 517) = 29469

GCD(57, 517) = ( 57 x 517 ) / 29469

= 57 / 517

= 57

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 342, 627, 517, 257 is 1
