The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 309 are 3 x 103

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

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

Given numbers are 691, 309, 918, 624

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

Apply this formula for all numbers.

Step1:

LCM(691, 309) = 213519

GCD(691, 309) = ( 691 x 309 ) / 213519

= 691 / 309

= 691

Step2:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 691, 309, 918, 624 is 1
