Given numbers are 664, 444, 865, 408

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 444 are 2 x 2 x 3 x 37

Prime factors of 865 are 5 x 173

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 664, 444, 865, 408

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

Apply this formula for all numbers.

Step1:

LCM(664, 444) = 73704

GCD(664, 444) = ( 664 x 444 ) / 73704

= 664 / 444

= 664

Step2:

LCM(4, 865) = 3460

GCD(4, 865) = ( 4 x 865 ) / 3460

= 4 / 865

= 4

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 664, 444, 865, 408 is 1
