Given numbers are 408, 280, 485, 517

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 485 are 5 x 97

Prime factors of 517 are 11 x 47

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

Given numbers are 408, 280, 485, 517

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

Apply this formula for all numbers.

Step1:

LCM(408, 280) = 14280

GCD(408, 280) = ( 408 x 280 ) / 14280

= 408 / 280

= 408

Step2:

LCM(8, 485) = 3880

GCD(8, 485) = ( 8 x 485 ) / 3880

= 8 / 485

= 8

Step3:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

So, Greatest Common Divisor of 408, 280, 485, 517 is 1
