Given numbers are 624, 456, 309, 553

The list of prime factors of all numbers are

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 309 are 3 x 103

Prime factors of 553 are 7 x 79

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

Given numbers are 624, 456, 309, 553

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

Apply this formula for all numbers.

Step1:

LCM(624, 456) = 11856

GCD(624, 456) = ( 624 x 456 ) / 11856

= 624 / 456

= 624

Step2:

LCM(24, 309) = 2472

GCD(24, 309) = ( 24 x 309 ) / 2472

= 24 / 309

= 24

Step3:

LCM(3, 553) = 1659

GCD(3, 553) = ( 3 x 553 ) / 1659

= 3 / 553

= 3

So, Greatest Common Divisor of 624, 456, 309, 553 is 1
