Given numbers are 165, 195, 425, 156

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 195 are 3 x 5 x 13

Prime factors of 425 are 5 x 5 x 17

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 165, 195, 425, 156

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

Apply this formula for all numbers.

Step1:

LCM(165, 195) = 2145

GCD(165, 195) = ( 165 x 195 ) / 2145

= 165 / 195

= 165

Step2:

LCM(15, 425) = 1275

GCD(15, 425) = ( 15 x 425 ) / 1275

= 15 / 425

= 15

Step3:

LCM(5, 156) = 780

GCD(5, 156) = ( 5 x 156 ) / 780

= 5 / 156

= 5

So, Greatest Common Divisor of 165, 195, 425, 156 is 1
