Given numbers are 515, 253, 756, 115

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 253 are 11 x 23

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 115 are 5 x 23

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

Given numbers are 515, 253, 756, 115

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

Apply this formula for all numbers.

Step1:

LCM(515, 253) = 130295

GCD(515, 253) = ( 515 x 253 ) / 130295

= 515 / 253

= 515

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 515, 253, 756, 115 is 1
