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

Step 1: Firstly, 1820 is divided by 2 to get 910.

Step 2: Now divide 910 by 2 to get 455.

Step 3: Then divide 455 by 5 to get 91.

Step 4: Divide 91 by 7 to get 13.

Here, 13 is a prime number that cannot be divided anymore.

So, the prime factorization of 1820 is: 2² × 5 × 7 × 13.

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