The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show -

Step 1: Firstly, 400 is divided by 2 to get 200.

Step 2: Now divide 200 by 2 to get 100.

Step 3: Then divide 100 by 2 to get 50.

Step 4: Divide 50 by 2 to get 25.

Step 5: Divide 25 by 5 to get 5. Here, 5 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 400 is: 24 × 52.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.

Positive factor pairs of 400: (1, 400), (2, 200), (4, 100), (5, 80), (8, 50), (10, 40), (16, 25).

Negative factor pairs of -400: (-1, -400), (-2, -200), (-4, -100), (-5, -80), (-8, -50), (-10, -40), (-16, -25).
