Step-by-step solution to find the factors and factor pairs of 161:
- If a whole number divides 161 evenly (remainder = 0), then it is a factor of 161 (divisor factor), and the corresponding quotient is also a factor of 161 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 161
- With the exception of 0, all whole numbers less than or equal to the square root of 161 (√161 ) are possible divisor factors of 161
- √161 = 12.6886
- Possible Divisor Factors of 161: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
- Filter list of possible divisor factors by testing divisibility of 161 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 161 (filtered): 1, 7, 11
- Divide 161 by the possible divisor factors in the filtered list
- Factors of 161: 1, 7, 23, 161
- Factor Pairs of 161: (1*161) (7*23)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
