Given numbers are 550, 648, 78, 323

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 78 are 2 x 3 x 13

Prime factors of 323 are 17 x 19

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

Given numbers are 550, 648, 78, 323

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

Apply this formula for all numbers.

Step1:

LCM(550, 648) = 178200

GCD(550, 648) = ( 550 x 648 ) / 178200

= 550 / 648

= 550

Step2:

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

= 2 / 78

= 2

Step3:

LCM(2, 323) = 646

GCD(2, 323) = ( 2 x 323 ) / 646

= 2 / 323

= 2

So, Greatest Common Divisor of 550, 648, 78, 323 is 1
