Given numbers are 623, 624, 856, 688

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

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

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

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 623, 624, 856, 688

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

Apply this formula for all numbers.

Step1:

LCM(623, 624) = 388752

GCD(623, 624) = ( 623 x 624 ) / 388752

= 623 / 624

= 623

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 623, 624, 856, 688 is 1
