Answer:

The GCF is 45

Step-by-step explanation:

<u>Step 1:  Find the prime factorization of each number </u>

<em>Prime Factorization of 90:</em>  2 * 3 * 3 * 5

<em>Prime Factorization of 45:</em>  3 * 3 * 5

<u>Step 2:  Multiply the numbers that they have in common </u>

Both numbers have 3, 3, and 5 in common.  

So we just multiply them:  3 * 3 * 5 = 45

Therefore, the GCF of 90 and 45 is:  45

Answer: The GCF is 45
