Given numbers are 688, 454, 447, 530

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 454 are 2 x 227

Prime factors of 447 are 3 x 149

Prime factors of 530 are 2 x 5 x 53

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

Given numbers are 688, 454, 447, 530

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

Apply this formula for all numbers.

Step1:

LCM(688, 454) = 156176

GCD(688, 454) = ( 688 x 454 ) / 156176

= 688 / 454

= 688

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 688, 454, 447, 530 is 1
