Given numbers are 684, 620, 798, 261

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 620 are 2 x 2 x 5 x 31

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

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 684, 620, 798, 261

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

Apply this formula for all numbers.

Step1:

LCM(684, 620) = 106020

GCD(684, 620) = ( 684 x 620 ) / 106020

= 684 / 620

= 684

Step2:

LCM(4, 798) = 1596

GCD(4, 798) = ( 4 x 798 ) / 1596

= 4 / 798

= 4

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 684, 620, 798, 261 is 1
