Given numbers are 685, 680, 253, 517

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

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 517 are 11 x 47

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

Given numbers are 685, 680, 253, 517

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

Apply this formula for all numbers.

Step1:

LCM(685, 680) = 93160

GCD(685, 680) = ( 685 x 680 ) / 93160

= 685 / 680

= 685

Step2:

LCM(5, 253) = 1265

GCD(5, 253) = ( 5 x 253 ) / 1265

= 5 / 253

= 5

Step3:

LCM(1, 517) = 517

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

= 1 / 517

= 1

So, Greatest Common Divisor of 685, 680, 253, 517 is 1
