The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows

Step 1: Firstly, 990 is divided by 2 to get 495.

Step 2: Now divide 495 by 3 to get 165.

Step 3: Then divide 165 by 3 to get 55.

Step 4: Divide 55 by 5 to get 11. Here, 11 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 990 is: 2 × 32 × 5 × 11.

Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs.

Both positive and negative factors constitute factor pairs.
