Let’s use the listing factors method here. The first step is to list all the factors of 90 and 270 separately. Once the factors of both numbers are listed, we can compare them and identify the common factors.

Step 1: List all the factors

Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Factors of 270: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

Step 2: Compare and identify common factors 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90 are the numbers that appear in both lists of factors.

Therefore, they are the common factors of 90 and 270.
