Question

A number which having more than two factors is called____________________number.

Answer 1

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than $1$and itself. Every positive integer is composite, prime, or the unit $1$, so the composite numbers are exactly the numbers that are not prime and not a unit.

For example, the integer $14$ is a composite number because it is the product of the two smaller integers $2\times 7$. Likewise, the integers $2$and $3$are not composite numbers because each of them can only be divided by one and itself.
