Step-by-step solution to find the factors and factor pairs of 621:
- If a whole number divides 621 evenly (remainder = 0), then it is a factor of 621 (divisor factor), and the corresponding quotient is also a factor of 621 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 621
- With the exception of 0, all whole numbers less than or equal to the square root of 621 (√621 ) are possible divisor factors of 621
- √621 = 24.9199
- Possible Divisor Factors of 621: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24
- Filter list of possible divisor factors by testing divisibility of 621 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 621 (filtered): 1, 3, 7, 9, 11, 13, 17, 19, 21, 23
- Divide 621 by the possible divisor factors in the filtered list
- Factors of 621: 1, 3, 9, 23, 27, 69, 207, 621
- Factor Pairs of 621: (1*621) (3*207) (9*69) (23*27)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
