Given numbers are 291, 239, 240, 165

The list of prime factors of all numbers are

Prime factors of 291 are 3 x 97

Prime factors of 239 are 239

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 291, 239, 240, 165

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

Apply this formula for all numbers.

Step1:

LCM(291, 239) = 69549

GCD(291, 239) = ( 291 x 239 ) / 69549

= 291 / 239

= 291

Step2:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 291, 239, 240, 165 is 1
