Given numbers are 517, 526, 305, 688

The list of prime factors of all numbers are

Prime factors of 517 are 11 x 47

Prime factors of 526 are 2 x 263

Prime factors of 305 are 5 x 61

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

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

Given numbers are 517, 526, 305, 688

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

Apply this formula for all numbers.

Step1:

LCM(517, 526) = 271942

GCD(517, 526) = ( 517 x 526 ) / 271942

= 517 / 526

= 517

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 517, 526, 305, 688 is 1
