Given numbers are 164, 346, 768, 639

The list of prime factors of all numbers are

Prime factors of 164 are 2 x 2 x 41

Prime factors of 346 are 2 x 173

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 164, 346, 768, 639

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

Apply this formula for all numbers.

Step1:

LCM(164, 346) = 28372

GCD(164, 346) = ( 164 x 346 ) / 28372

= 164 / 346

= 164

Step2:

LCM(2, 768) = 768

GCD(2, 768) = ( 2 x 768 ) / 768

= 2 / 768

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 164, 346, 768, 639 is 1
