Given numbers are 156, 561, 285, 329

The list of prime factors of all numbers are

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

Prime factors of 561 are 3 x 11 x 17

Prime factors of 285 are 3 x 5 x 19

Prime factors of 329 are 7 x 47

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

Given numbers are 156, 561, 285, 329

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

Apply this formula for all numbers.

Step1:

LCM(156, 561) = 29172

GCD(156, 561) = ( 156 x 561 ) / 29172

= 156 / 561

= 156

Step2:

LCM(3, 285) = 285

GCD(3, 285) = ( 3 x 285 ) / 285

= 3 / 285

= 3

Step3:

LCM(3, 329) = 987

GCD(3, 329) = ( 3 x 329 ) / 987

= 3 / 329

= 3

So, Greatest Common Divisor of 156, 561, 285, 329 is 1
