Given numbers are 646, 260, 854, 459

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 854 are 2 x 7 x 61

Prime factors of 459 are 3 x 3 x 3 x 17

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

Given numbers are 646, 260, 854, 459

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

Apply this formula for all numbers.

Step1:

LCM(646, 260) = 83980

GCD(646, 260) = ( 646 x 260 ) / 83980

= 646 / 260

= 646

Step2:

LCM(2, 854) = 854

GCD(2, 854) = ( 2 x 854 ) / 854

= 2 / 854

= 2

Step3:

LCM(2, 459) = 918

GCD(2, 459) = ( 2 x 459 ) / 918

= 2 / 459

= 2

So, Greatest Common Divisor of 646, 260, 854, 459 is 1
