Step-by-step solution to find the factors and factor pairs of 91:
- If a whole number divides 91 evenly (remainder = 0), then it is a factor of 91 (divisor factor), and the corresponding quotient is also a factor of 91 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 91
- With the exception of 0, all whole numbers less than or equal to the square root of 91 (√91 ) are possible divisor factors of 91
- √91 = 9.5394
- Possible Divisor Factors of 91: 1, 2, 3, 4, 5, 6, 7, 8, 9
- Filter list of possible divisor factors by testing divisibility of 91 by 2, 3, 4, 5, and 9
- Possible Divisor Factors of 91 (filtered): 1, 7
- Divide 91 by the possible divisor factors in the filtered list
- Factors of 91: 1, 7, 13, 91
- Factor Pairs of 91: (1*91) (7*13)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
