Step-by-step solution to find the factors and factor pairs of 15:
- If a whole number divides 15 evenly (remainder = 0), then it is a factor of 15 (divisor factor), and the corresponding quotient is also a factor of 15 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 15
- With the exception of 0, all whole numbers less than or equal to the square root of 15 (√15 ) are possible divisor factors of 15
- √15 = 3.873
- Possible Divisor Factors of 15: 1, 2, 3
- Filter list of possible divisor factors by testing divisibility of 15 by 2 and 3
- Possible Divisor Factors of 15 (filtered): 1, 3
- Divide 15 by the possible divisor factors in the filtered list
- Factors of 15: 1, 3, 5, 15
- Factor Pairs of 15: (1*15) (3*5)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
