Given numbers are 680, 253, 556, 517

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 253 are 11 x 23

Prime factors of 556 are 2 x 2 x 139

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 680, 253, 556, 517

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

Apply this formula for all numbers.

Step1:

LCM(680, 253) = 172040

GCD(680, 253) = ( 680 x 253 ) / 172040

= 680 / 253

= 680

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 517) = 517

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

= 1 / 517

= 1

So, Greatest Common Divisor of 680, 253, 556, 517 is 1
