Given numbers are 255, 560, 305, 291

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 305 are 5 x 61

Prime factors of 291 are 3 x 97

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

Given numbers are 255, 560, 305, 291

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

Apply this formula for all numbers.

Step1:

LCM(255, 560) = 28560

GCD(255, 560) = ( 255 x 560 ) / 28560

= 255 / 560

= 255

Step2:

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

= 5 / 305

= 5

Step3:

LCM(5, 291) = 1455

GCD(5, 291) = ( 5 x 291 ) / 1455

= 5 / 291

= 5

So, Greatest Common Divisor of 255, 560, 305, 291 is 1
