Given numbers are 342, 168, 325, 646

The list of prime factors of all numbers are

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

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 325 are 5 x 5 x 13

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 342, 168, 325, 646

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

Apply this formula for all numbers.

Step1:

LCM(342, 168) = 9576

GCD(342, 168) = ( 342 x 168 ) / 9576

= 342 / 168

= 342

Step2:

LCM(6, 325) = 1950

GCD(6, 325) = ( 6 x 325 ) / 1950

= 6 / 325

= 6

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 342, 168, 325, 646 is 1
