Step-by-step solution to find the factors and factor pairs of 423:
- If a whole number divides 423 evenly (remainder = 0), then it is a factor of 423 (divisor factor), and the corresponding quotient is also a factor of 423 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 423
- With the exception of 0, all whole numbers less than or equal to the square root of 423 (√423 ) are possible divisor factors of 423
- √423 = 20.567
- Possible Divisor Factors of 423: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
- Filter list of possible divisor factors by testing divisibility of 423 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 423 (filtered): 1, 3, 7, 9, 11, 13, 17, 19
- Divide 423 by the possible divisor factors in the filtered list
- Factors of 423: 1, 3, 9, 47, 141, 423
- Factor Pairs of 423: (1*423) (3*141) (9*47)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
