Given numbers are 660, 717, 485, 449

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 717 are 3 x 239

Prime factors of 485 are 5 x 97

Prime factors of 449 are 449

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

Given numbers are 660, 717, 485, 449

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

Apply this formula for all numbers.

Step1:

LCM(660, 717) = 157740

GCD(660, 717) = ( 660 x 717 ) / 157740

= 660 / 717

= 660

Step2:

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

= 3 / 485

= 3

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 660, 717, 485, 449 is 1
