Given numbers are 549, 576, 780, 856

The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

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

Prime factors of 856 are 2 x 2 x 2 x 107

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

Given numbers are 549, 576, 780, 856

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

Apply this formula for all numbers.

Step1:

LCM(549, 576) = 35136

GCD(549, 576) = ( 549 x 576 ) / 35136

= 549 / 576

= 549

Step2:

LCM(9, 780) = 2340

GCD(9, 780) = ( 9 x 780 ) / 2340

= 9 / 780

= 9

Step3:

LCM(3, 856) = 2568

GCD(3, 856) = ( 3 x 856 ) / 2568

= 3 / 856

= 3

So, Greatest Common Divisor of 549, 576, 780, 856 is 1
