Given numbers are 515, 390, 255, 669

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 255 are 3 x 5 x 17

Prime factors of 669 are 3 x 223

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

Given numbers are 515, 390, 255, 669

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

Apply this formula for all numbers.

Step1:

LCM(515, 390) = 40170

GCD(515, 390) = ( 515 x 390 ) / 40170

= 515 / 390

= 515

Step2:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

Step3:

LCM(5, 669) = 3345

GCD(5, 669) = ( 5 x 669 ) / 3345

= 5 / 669

= 5

So, Greatest Common Divisor of 515, 390, 255, 669 is 1
