Given numbers are 428, 818, 864, 805

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 818 are 2 x 409

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

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 428, 818, 864, 805

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

Apply this formula for all numbers.

Step1:

LCM(428, 818) = 175052

GCD(428, 818) = ( 428 x 818 ) / 175052

= 428 / 818

= 428

Step2:

LCM(2, 864) = 864

GCD(2, 864) = ( 2 x 864 ) / 864

= 2 / 864

= 2

Step3:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

So, Greatest Common Divisor of 428, 818, 864, 805 is 1
