Step-by-step solution to find the factors and factor pairs of 243:
- If a whole number divides 243 evenly (remainder = 0), then it is a factor of 243 (divisor factor), and the corresponding quotient is also a factor of 243 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 243
- With the exception of 0, all whole numbers less than or equal to the square root of 243 (√243 ) are possible divisor factors of 243
- √243 = 15.5885
- Possible Divisor Factors of 243: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
- Filter list of possible divisor factors by testing divisibility of 243 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 243 (filtered): 1, 3, 7, 9, 11, 13
- Divide 243 by the possible divisor factors in the filtered list
- Factors of 243: 1, 3, 9, 27, 81, 243
- Factor Pairs of 243: (1*243) (3*81) (9*27)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
