Step-by-step solution to find the factors and factor pairs of 687:
- If a whole number divides 687 evenly (remainder = 0), then it is a factor of 687 (divisor factor), and the corresponding quotient is also a factor of 687 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 687
- With the exception of 0, all whole numbers less than or equal to the square root of 687 (√687 ) are possible divisor factors of 687
- √687 = 26.2107
- Possible Divisor Factors of 687: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26
- Filter list of possible divisor factors by testing divisibility of 687 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 687 (filtered): 1, 3, 7, 11, 13, 17, 19, 21, 23
- Divide 687 by the possible divisor factors in the filtered list
- Factors of 687: 1, 3, 229, 687
- Factor Pairs of 687: (1*687) (3*229)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
