Given numbers are 688, 442, 281, 517

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 442 are 2 x 13 x 17

Prime factors of 281 are 281

Prime factors of 517 are 11 x 47

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

Given numbers are 688, 442, 281, 517

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

Apply this formula for all numbers.

Step1:

LCM(688, 442) = 152048

GCD(688, 442) = ( 688 x 442 ) / 152048

= 688 / 442

= 688

Step2:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

Step3:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

So, Greatest Common Divisor of 688, 442, 281, 517 is 1
