Given numbers are 780, 355, 961, 936

The list of prime factors of all numbers are

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

Prime factors of 355 are 5 x 71

Prime factors of 961 are 31 x 31

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Given numbers are 780, 355, 961, 936

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

Apply this formula for all numbers.

Step1:

LCM(780, 355) = 55380

GCD(780, 355) = ( 780 x 355 ) / 55380

= 780 / 355

= 780

Step2:

LCM(5, 961) = 4805

GCD(5, 961) = ( 5 x 961 ) / 4805

= 5 / 961

= 5

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 780, 355, 961, 936 is 1
