With the help of divisibility rules, find out the smallest factor of the given number. Here, 36 is an even number. ...
36 ÷ 2 = 18. ...
18 ÷ 2 = 9. ...
9 ÷ 3 = 3. ...
Prime factorization of 36 using upside-down division method is 2 × 2 × 3 × 3 = 2² × 3².
- 18 -
we branch out 18 into its prime factors. So, the prime factorization of 18 is 18= 2 × 3 × 3.
A factor tree is not unique for a given number. Instead of expressing 18 as 2 × 9, we can express 18 as 3 × 6.
