The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 965 are 5 x 193

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

Given numbers are 549, 520, 640, 965

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

Apply this formula for all numbers.

Step1:

LCM(549, 520) = 285480

GCD(549, 520) = ( 549 x 520 ) / 285480

= 549 / 520

= 549

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 549, 520, 640, 965 is 1
