Given numbers are 815, 438, 864, 195

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 438 are 2 x 3 x 73

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

Prime factors of 195 are 3 x 5 x 13

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

Given numbers are 815, 438, 864, 195

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

Apply this formula for all numbers.

Step1:

LCM(815, 438) = 356970

GCD(815, 438) = ( 815 x 438 ) / 356970

= 815 / 438

= 815

Step2:

LCM(1, 864) = 864

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

= 1 / 864

= 1

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 815, 438, 864, 195 is 1
