Given numbers are 823, 780, 822, 539

The list of prime factors of all numbers are

Prime factors of 823 are 823

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

Prime factors of 822 are 2 x 3 x 137

Prime factors of 539 are 7 x 7 x 11

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

Given numbers are 823, 780, 822, 539

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

Apply this formula for all numbers.

Step1:

LCM(823, 780) = 641940

GCD(823, 780) = ( 823 x 780 ) / 641940

= 823 / 780

= 823

Step2:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 823, 780, 822, 539 is 1
