What is the definition of factors?
When certain numbers are multiplied together they produce a product, in that case the numbers used are defined as the factors of the product obtained. A factor of a number can be positive or negative.
Properties of Factors
- Every number is a factor of zero (0), since 91 x 0 = 0.
- Every number other than 1 has at least two factors, namely the number itself and 1.
- Every factor of a number is an exact divisor of that number, example 1, 7, 13, 91 are exact divisors of 91.
- Factors of 91 are 1, 7, 13, 91. Each factor divides 91 without leaving a remainder.
- Every number consists of one common and smallest factor and that is number 1.
