Step-by-step solution to find the factors and factor pairs of 121:
- If a whole number divides 121 evenly (remainder = 0), then it is a factor of 121 (divisor factor), and the corresponding quotient is also a factor of 121 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 121
- With the exception of 0, all whole numbers less than or equal to the square root of 121 (√121 ) are possible divisor factors of 121
- √121 = 11
- Possible Divisor Factors of 121: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
- Filter list of possible divisor factors by testing divisibility of 121 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 121 (filtered): 1, 7, 11
- Divide 121 by the possible divisor factors in the filtered list
- Factors of 121: 1, 11, 121
- Factor Pairs of 121: (1*121) (11*11)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
