Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 731,815, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 731,815 | |
| -1 | -731,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 731,815.
Example:
1 x 731,815 = 731,815
and
-1 x -731,815 = 731,815
Notice both answers equal 731,815
With that explanation out of the way, let's continue. Next, we take the number 731,815 and divide it by 2:
731,815 ÷ 2 = 365,907.5
If the quotient is a whole number, then 2 and 365,907.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 731,815 | |
| -1 | -731,815 |
Now, we try dividing 731,815 by 3:
731,815 ÷ 3 = 243,938.3333
If the quotient is a whole number, then 3 and 243,938.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 731,815 | |
| -1 | -731,815 |
Let's try dividing by 4:
731,815 ÷ 4 = 182,953.75
If the quotient is a whole number, then 4 and 182,953.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 731,815 | |
| -1 | 731,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 49 | 103 | 145 | 203 | 245 | 515 | 721 | 1,015 | 1,421 | 2,987 | 3,605 | 5,047 | 7,105 | 14,935 | 20,909 | 25,235 | 104,545 | 146,363 | 731,815 |
| -1 | -5 | -7 | -29 | -35 | -49 | -103 | -145 | -203 | -245 | -515 | -721 | -1,015 | -1,421 | -2,987 | -3,605 | -5,047 | -7,105 | -14,935 | -20,909 | -25,235 | -104,545 | -146,363 | -731,815 |
