The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 261 are 3 x 3 x 29

Prime factors of 961 are 31 x 31

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

Given numbers are 783, 756, 261, 961

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

Apply this formula for all numbers.

Step1:

LCM(783, 756) = 21924

GCD(783, 756) = ( 783 x 756 ) / 21924

= 783 / 756

= 783

Step2:

LCM(27, 261) = 783

GCD(27, 261) = ( 27 x 261 ) / 783

= 27 / 261

= 27

Step3:

LCM(9, 961) = 8649

GCD(9, 961) = ( 9 x 961 ) / 8649

= 9 / 961

= 9

So, Greatest Common Divisor of 783, 756, 261, 961 is 1
