The list of prime factors of all numbers are

Prime factors of 547 are 547

Prime factors of 977 are 977

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

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

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

Given numbers are 547, 977, 780, 819

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

Apply this formula for all numbers.

Step1:

LCM(547, 977) = 534419

GCD(547, 977) = ( 547 x 977 ) / 534419

= 547 / 977

= 547

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 819) = 819

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

= 1 / 819

= 1

So, Greatest Common Divisor of 547, 977, 780, 819 is 1
