Given numbers are 326, 961, 819, 780

The list of prime factors of all numbers are

Prime factors of 326 are 2 x 163

Prime factors of 961 are 31 x 31

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 326, 961, 819, 780

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

Apply this formula for all numbers.

Step1:

LCM(326, 961) = 313286

GCD(326, 961) = ( 326 x 961 ) / 313286

= 326 / 961

= 326

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 326, 961, 819, 780 is 1
