Given numbers are 487, 459, 660, 805

The list of prime factors of all numbers are

Prime factors of 487 are 487

Prime factors of 459 are 3 x 3 x 3 x 17

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

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 487, 459, 660, 805

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

Apply this formula for all numbers.

Step1:

LCM(487, 459) = 223533

GCD(487, 459) = ( 487 x 459 ) / 223533

= 487 / 459

= 487

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 487, 459, 660, 805 is 1
