Given numbers are 665, 242, 560, 864

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 242 are 2 x 11 x 11

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

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

Given numbers are 665, 242, 560, 864

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

Apply this formula for all numbers.

Step1:

LCM(665, 242) = 160930

GCD(665, 242) = ( 665 x 242 ) / 160930

= 665 / 242

= 665

Step2:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 665, 242, 560, 864 is 1
