The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 646 are 2 x 17 x 19

Prime factors of 410 are 2 x 5 x 41

Prime factors of 865 are 5 x 173

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

Given numbers are 454, 646, 410, 865

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

Apply this formula for all numbers.

Step1:

LCM(454, 646) = 146642

GCD(454, 646) = ( 454 x 646 ) / 146642

= 454 / 646

= 454

Step2:

LCM(2, 410) = 410

GCD(2, 410) = ( 2 x 410 ) / 410

= 2 / 410

= 2

Step3:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

So, Greatest Common Divisor of 454, 646, 410, 865 is 1
