To solve this problem, we need to find the greatest common divisor (GCD) of the number of each type of flower available. The florist has:
- 36 roses
- 27 tulips
- 18 carnations
We start by finding the GCD of these three numbers.
-
Finding the prime factorization of each number:
- The prime factorization of 36 is \(2^2 \times 3^2\).
- The prime factorization of 27 is \(3^3\).
- The prime factorization of 18 is \(2^1 \times 3^2\).
-
Identifying the common prime factors:
The only prime factor that appears in all three factorizations is 3.
-
Finding the minimum exponent:
- For 3:
- In 36, the exponent is 2.
- In 27, the exponent is 3.
- In 18, the exponent is 2.
- The minimum exponent for 3 is \(2\).
- For 3:
Since the number 2 from the prime factorization of the flowers does not appear in all three numbers, we only consider the factor \(3^2\).
Thus, the GCD of 36, 27, and 18 is:
\[ GCD = 3^2 = 9 \]
- Calculation of the largest number of bouquets:
The largest number of bouquets the florist can create, where each bouquet contains an equal number of each type of flower without any left over, is therefore:
\[ \boxed{9} \]
