Epinephrine The inclusion of epinephrine in a dental office emergency kit is mandatory for the treatment of cardiac arrest and overwhelming anaphylaxis. However, it must be emphasized that these extreme conditions are the only situations that would require its use in the dental office emergency.
GCD- In mathematics, the greatest common divisor (gcd), also known as the greatest common factor (gcf), or highest common factor (hcf), of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder.
3 is the GCD of 6 and 9 because it's the largest number they can be divided by. So we'll divide the numerator by 3. 6 divided by 3 is 2. Then we'll divide the denominator by 3. 9 divided by 3 is 3. Now we've reduced 6/9 to 2/3, which is its simplest form.
