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

Given numbers are 780, 987, 837, 823

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

Apply this formula for all numbers.

Step1:

LCM(780, 987) = 256620

GCD(780, 987) = ( 780 x 987 ) / 256620

= 780 / 987

= 780

Step2:

LCM(3, 837) = 837

GCD(3, 837) = ( 3 x 837 ) / 837

= 3 / 837

= 3

Step3:

LCM(3, 823) = 2469

GCD(3, 823) = ( 3 x 823 ) / 2469

= 3 / 823

= 3

So, Greatest Common Divisor of 780, 987, 837, 823 is 1
