Given numbers are 688, 530, 992, 457

The list of prime factors of all numbers are

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

Prime factors of 530 are 2 x 5 x 53

Prime factors of 992 are 2 x 2 x 2 x 2 x 2 x 31

Prime factors of 457 are 457

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

Given numbers are 688, 530, 992, 457

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

Apply this formula for all numbers.

Step1:

LCM(688, 530) = 182320

GCD(688, 530) = ( 688 x 530 ) / 182320

= 688 / 530

= 688

Step2:

LCM(2, 992) = 992

GCD(2, 992) = ( 2 x 992 ) / 992

= 2 / 992

= 2

Step3:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

So, Greatest Common Divisor of 688, 530, 992, 457 is 1
