Step-by-step solution to find the factors and factor pairs of 189:
- If a whole number divides 189 evenly (remainder = 0), then it is a factor of 189 (divisor factor), and the corresponding quotient is also a factor of 189 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 189
- With the exception of 0, all whole numbers less than or equal to the square root of 189 (√189 ) are possible divisor factors of 189
- √189 = 13.7477
- Possible Divisor Factors of 189: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
- Filter list of possible divisor factors by testing divisibility of 189 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 189 (filtered): 1, 3, 7, 9, 11, 13
- Divide 189 by the possible divisor factors in the filtered list
- Factors of 189: 1, 3, 7, 9, 21, 27, 63, 189
- Factor Pairs of 189: (1*189) (3*63) (7*27) (9*21)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
