Given numbers are 688, 714, 657, 485

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 714 are 2 x 3 x 7 x 17

Prime factors of 657 are 3 x 3 x 73

Prime factors of 485 are 5 x 97

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

Given numbers are 688, 714, 657, 485

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

Apply this formula for all numbers.

Step1:

LCM(688, 714) = 245616

GCD(688, 714) = ( 688 x 714 ) / 245616

= 688 / 714

= 688

Step2:

LCM(2, 657) = 1314

GCD(2, 657) = ( 2 x 657 ) / 1314

= 2 / 657

= 2

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 688, 714, 657, 485 is 1
