To find the greatest number of poster boards Gloria can make, we need to find the greatest common factor of the three numbers: 18, 9, and 12.
The prime factorization of 18 is 2 * 3 * 3.
The prime factorization of 9 is 3 * 3.
The prime factorization of 12 is 2 * 2 * 3.
Taking the highest exponent for each prime factor, the greatest common factor is 2 * 3 * 3 = 18.
Therefore, Gloria can make 18 poster boards using all of the stamps.
