Given numbers are 247, 260, 259, 291

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 259 are 7 x 37

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 247, 260, 259, 291

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

Apply this formula for all numbers.

Step1:

LCM(247, 260) = 4940

GCD(247, 260) = ( 247 x 260 ) / 4940

= 247 / 260

= 247

Step2:

LCM(13, 259) = 3367

GCD(13, 259) = ( 13 x 259 ) / 3367

= 13 / 259

= 13

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 247, 260, 259, 291 is 1
