Step-by-step solution to find the factors and factor pairs of 441:
- If a whole number divides 441 evenly (remainder = 0), then it is a factor of 441 (divisor factor), and the corresponding quotient is also a factor of 441 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 441
- With the exception of 0, all whole numbers less than or equal to the square root of 441 (√441 ) are possible divisor factors of 441
- √441 = 21
- Possible Divisor Factors of 441: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21
- Filter list of possible divisor factors by testing divisibility of 441 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 441 (filtered): 1, 3, 7, 9, 11, 13, 17, 19, 21
- Divide 441 by the possible divisor factors in the filtered list
- Factors of 441: 1, 3, 7, 9, 21, 49, 63, 147, 441
- Factor Pairs of 441: (1*441) (3*147) (7*63) (9*49) (21*21)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
