{\text{All composite numbers have at least three factors this means that there are at least three numbers }} \\

{\text{that can be used to evenly divide a composite number}}{\text{.}} \\

{\text{e}}{\text{.g 21}} \\

{\text{Factors of 21 are 1,3,7,21}} \\

{\text{Hence smallest composite no is 4 }} \\

{\text{Because, }} \\

{\text{1 has only one factor }} \\

{\text{2 has 2 factors i}}{\text{.e 1 and 2 }} \\

{\text{Also, 3 has 2 factors i}}{\text{.e 1 and 3 }} \\

{\text{So, 4 is the first number that satisfies all the conditions to be a composite number }} \\

{\text{Factors of 4 are 1,2,4}} \\

{\text{NOTE: A composite number is a positive integer that can be formed by multiplying two}} \\

{\text{Smaller positive integers }}{\text{.equivalently,it is a positive integer that has at least one divisor}} \\
