Given numbers are 689, 520, 170, 165

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 170 are 2 x 5 x 17

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 689, 520, 170, 165

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

Apply this formula for all numbers.

Step1:

LCM(689, 520) = 27560

GCD(689, 520) = ( 689 x 520 ) / 27560

= 689 / 520

= 689

Step2:

LCM(13, 170) = 2210

GCD(13, 170) = ( 13 x 170 ) / 2210

= 13 / 170

= 13

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 689, 520, 170, 165 is 1
