Given numbers are 249, 681, 810, 515

The list of prime factors of all numbers are

Prime factors of 249 are 3 x 83

Prime factors of 681 are 3 x 227

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 515 are 5 x 103

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

Given numbers are 249, 681, 810, 515

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

Apply this formula for all numbers.

Step1:

LCM(249, 681) = 56523

GCD(249, 681) = ( 249 x 681 ) / 56523

= 249 / 681

= 249

Step2:

LCM(3, 810) = 810

GCD(3, 810) = ( 3 x 810 ) / 810

= 3 / 810

= 3

Step3:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

So, Greatest Common Divisor of 249, 681, 810, 515 is 1
