There isn't one for 3. If your teacher or someone assigned you make a factor tree for 3 they're wrong. Unless you want to use 1x3 but that doesn't count.

Unless you specify a number, there are an infinite number of answers to this question.
Add up the digits of the given number. If they total a multiple of three, the number has three as a factor.
That's finding the prime factorization.
Factors are numbers we can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 × 3 = 6. A number can have MANY factors!So, an easy way of finding your answers is to look at a timetable charts and analyze what equals to 2,4 and #5.
The first step to finding the common prime factors is to list the prime factors of both numbers. For 12 and 45, the prime factors are: 12 = 2x2x3 45 = 3x3x5 The next step is to identify which prime factors are shared by both. In this case, both use a 3. Thus, 3 is the only common prime factor of 12 and 45.
When you are finding common factors, one method is to list the factors.
The factors of 117 are 1,3,9,13,39,and 117The factors of 117 are 1, 3, 9, 13, 39, and 117.1,3,9,13,39,and 1171x117;3x39;9x13To find the factors of a number, it is helpful to know the rules for checking if something is a divisor. One rule is that if a numbers digits add up to 9, the number divides by 9. In this case, 117 has digits which add up to 9, and so can be divided by 9. If we do this, we get 13, which is prime. Thus the prime factors are 3, 3 and 13. These can be combined to get the other factors. Therefore the factors of 117 are 1, 3, 9, 13, 39 and 117.
