Step-by-step solution to find the factors and factor pairs of 20:
- If a whole number divides 20 evenly (remainder = 0), then it is a factor of 20 (divisor factor), and the corresponding quotient is also a factor of 20 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 20
- With the exception of 0, all whole numbers less than or equal to the square root of 20 (√20 ) are possible divisor factors of 20
- √20 = 4.4721
- Possible Divisor Factors of 20: 1, 2, 3, 4
- Filter list of possible divisor factors by testing divisibility of 20 by 2, 3, and 4
- Possible Divisor Factors of 20 (filtered): 1, 2, 4
- Divide 20 by the possible divisor factors in the filtered list
- Factors of 20: 1, 2, 4, 5, 10, 20
- Factor Pairs of 20: (1*20) (2*10) (4*5)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
