Given numbers are 665, 864, 308, 417

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 417 are 3 x 139

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

Given numbers are 665, 864, 308, 417

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

Apply this formula for all numbers.

Step1:

LCM(665, 864) = 574560

GCD(665, 864) = ( 665 x 864 ) / 574560

= 665 / 864

= 665

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 665, 864, 308, 417 is 1
