Given numbers are 804, 686, 676, 687

The list of prime factors of all numbers are

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

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 687 are 3 x 229

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

Given numbers are 804, 686, 676, 687

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

Apply this formula for all numbers.

Step1:

LCM(804, 686) = 275772

GCD(804, 686) = ( 804 x 686 ) / 275772

= 804 / 686

= 804

Step2:

LCM(2, 676) = 676

GCD(2, 676) = ( 2 x 676 ) / 676

= 2 / 676

= 2

Step3:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

So, Greatest Common Divisor of 804, 686, 676, 687 is 1
