Step-by-step solution to find the factors and factor pairs of 261:
- If a whole number divides 261 evenly (remainder = 0), then it is a factor of 261 (divisor factor), and the corresponding quotient is also a factor of 261 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 261
- With the exception of 0, all whole numbers less than or equal to the square root of 261 (√261 ) are possible divisor factors of 261
- √261 = 16.1555
- Possible Divisor Factors of 261: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
- Filter list of possible divisor factors by testing divisibility of 261 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 261 (filtered): 1, 3, 7, 9, 11, 13
- Divide 261 by the possible divisor factors in the filtered list
- Factors of 261: 1, 3, 9, 29, 87, 261
- Factor Pairs of 261: (1*261) (3*87) (9*29)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
