How can we define factors?
In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.
Properties of Factors
- Each number is a factor of itself. Eg. 156 and 3080 are factors of themselves respectively.
- 1 is a factor of every number. Eg. 1 is a factor of 156 and also of 3080.
- Every number is a factor of zero (0), since 156 x 0 = 0 and 3080 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, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 are exact divisors of 156 and 1, 2, 4, 5, 7, 8, 10, 11, 14, 20, 22, 28, 35, 40, 44, 55, 56, 70, 77, 88, 110, 140, 154, 220, 280, 308, 385, 440, 616, 770, 1540, 3080 are exact divisors of 3080.
- Factors of 156 are 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156. Each factor divides 156 without leaving a remainder.
Simlarly, factors of 3080 are 1, 2, 4, 5, 7, 8, 10, 11, 14, 20, 22, 28, 35, 40, 44, 55, 56, 70, 77, 88, 110, 140, 154, 220, 280, 308, 385, 440, 616, 770, 1540, 3080. Each factor divides 3080 without leaving a remainder. - Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 are all less than or equal to 156 and 1, 2, 4, 5, 7, 8, 10, 11, 14, 20, 22, 28, 35, 40, 44, 55, 56, 70, 77, 88, 110, 140, 154, 220, 280, 308, 385, 440, 616, 770, 1540, 3080 are all less than or equal to 3080.
