<p>A<a>number</a>to be identified as a<a>prime number</a>: the number should not have more than two <a>factors</a>, that too only 1 and itself, or else it is a<a>composite number</a>. 48 is not a prime number, since factors of 48 are 1,2,3,4,6,8,12,16,24, and 48, where the count of factors is more than two, hence, it is not a prime number. So, we can say that 48 is a composite number.</p>

<p>The only condition this method involves is that a particular number is prime if and only if it has two distinct<a>integers</a>as its divisors. In the case of 48, the distinct divisors are: 1,2,3,4,6,8,12,16,24, and 48. Hence, there exist more than two divisors of 48. Hence, 48 is not prime. </p>

<p>The number 48 is written on top and two branches are extended.</p>
37
<p>Fill in those branches with a factor pair of the number above, i.e., 48. Continue this process until each branch ends with a prime factor (number). The first two branches of the<a>factor tree</a>of 48 are 2 and 24, then proceeding to 24, we get 2 and 12. For 12, it is 2 and 6, and again proceeding to 6, we get 2 and 3.</p>
