Given numbers are 515, 102, 810, 206

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 102 are 2 x 3 x 17

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

Prime factors of 206 are 2 x 103

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

Given numbers are 515, 102, 810, 206

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

Apply this formula for all numbers.

Step1:

LCM(515, 102) = 52530

GCD(515, 102) = ( 515 x 102 ) / 52530

= 515 / 102

= 515

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 515, 102, 810, 206 is 1
