Given numbers are 305, 309, 336, 156

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 309 are 3 x 103

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

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 305, 309, 336, 156

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

Apply this formula for all numbers.

Step1:

LCM(305, 309) = 94245

GCD(305, 309) = ( 305 x 309 ) / 94245

= 305 / 309

= 305

Step2:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 305, 309, 336, 156 is 1
