Given numbers are 815, 804, 336, 438

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 815, 804, 336, 438

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

Apply this formula for all numbers.

Step1:

LCM(815, 804) = 655260

GCD(815, 804) = ( 815 x 804 ) / 655260

= 815 / 804

= 815

Step2:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 815, 804, 336, 438 is 1
