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

Step 1: Firstly, -420 is divided by -1 to get 420.

Step 2: Now divide 420 by 2 to get 210.

Step 3: Then divide 210 by 2 to get 105.

Step 4: Divide 105 by 3 to get 35.

Step 5: Divide 35 by 5 to get 7. Here, 7 is the smallest prime number that cannot be divided anymore. So, the prime factorization of -420 is: -1 × 2² × 3 × 5 × 7.

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