Given numbers are 165, 345, 346, 665

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 345 are 3 x 5 x 23

Prime factors of 346 are 2 x 173

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 165, 345, 346, 665

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

Apply this formula for all numbers.

Step1:

LCM(165, 345) = 3795

GCD(165, 345) = ( 165 x 345 ) / 3795

= 165 / 345

= 165

Step2:

LCM(15, 346) = 5190

GCD(15, 346) = ( 15 x 346 ) / 5190

= 15 / 346

= 15

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 165, 345, 346, 665 is 1
