To draw a factor tree for 900, we start by dividing it by its smallest prime factor, which is 2. 900 ÷ 2 = 450 Next, we continue dividing the resulting quotient by its smallest prime factor. 450 ÷ 2 = 225 Now, we divide 225 by its smallest prime factor, which is 3. 225 ÷ 3 = 75 Finally, we have 75 left, and its only prime factor is itself. 75 ÷ 75 = 1 So, the factor tree for 900 is: 900 / 2 450 / 2 225 / 3 75 / 75

Use a factor tree. 75 25,3 5,5,3
23 is a prime number. No prime factorization. No tree.
13 is already prime. It doesn't need a tree.
