Given numbers are 688, 102, 183, 257

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 102 are 2 x 3 x 17

Prime factors of 183 are 3 x 61

Prime factors of 257 are 257

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

Given numbers are 688, 102, 183, 257

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

Apply this formula for all numbers.

Step1:

LCM(688, 102) = 35088

GCD(688, 102) = ( 688 x 102 ) / 35088

= 688 / 102

= 688

Step2:

LCM(2, 183) = 366

GCD(2, 183) = ( 2 x 183 ) / 366

= 2 / 183

= 2

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 688, 102, 183, 257 is 1
