Given numbers are 490, 676, 798, 865

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 798 are 2 x 3 x 7 x 19

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 490, 676, 798, 865

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

Apply this formula for all numbers.

Step1:

LCM(490, 676) = 165620

GCD(490, 676) = ( 490 x 676 ) / 165620

= 490 / 676

= 490

Step2:

LCM(2, 798) = 798

GCD(2, 798) = ( 2 x 798 ) / 798

= 2 / 798

= 2

Step3:

LCM(2, 865) = 1730

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

= 2 / 865

= 2

So, Greatest Common Divisor of 490, 676, 798, 865 is 1
