Given numbers are 115, 260, 297, 688

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

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

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 115, 260, 297, 688

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

Apply this formula for all numbers.

Step1:

LCM(115, 260) = 5980

GCD(115, 260) = ( 115 x 260 ) / 5980

= 115 / 260

= 115

Step2:

LCM(5, 297) = 1485

GCD(5, 297) = ( 5 x 297 ) / 1485

= 5 / 297

= 5

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 115, 260, 297, 688 is 1
