Given numbers are 665, 170, 663, 580

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 170 are 2 x 5 x 17

Prime factors of 663 are 3 x 13 x 17

Prime factors of 580 are 2 x 2 x 5 x 29

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

Given numbers are 665, 170, 663, 580

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

Apply this formula for all numbers.

Step1:

LCM(665, 170) = 22610

GCD(665, 170) = ( 665 x 170 ) / 22610

= 665 / 170

= 665

Step2:

LCM(5, 663) = 3315

GCD(5, 663) = ( 5 x 663 ) / 3315

= 5 / 663

= 5

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 665, 170, 663, 580 is 1
