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 1,345,825, 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 | 1,345,825 | |
| -1 | -1,345,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,345,825.
Example:
1 x 1,345,825 = 1,345,825
and
-1 x -1,345,825 = 1,345,825
Notice both answers equal 1,345,825
With that explanation out of the way, let's continue. Next, we take the number 1,345,825 and divide it by 2:
1,345,825 ÷ 2 = 672,912.5
If the quotient is a whole number, then 2 and 672,912.5 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 | 1,345,825 | |
| -1 | -1,345,825 |
Now, we try dividing 1,345,825 by 3:
1,345,825 ÷ 3 = 448,608.3333
If the quotient is a whole number, then 3 and 448,608.3333 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 | 1,345,825 | |
| -1 | -1,345,825 |
Let's try dividing by 4:
1,345,825 ÷ 4 = 336,456.25
If the quotient is a whole number, then 4 and 336,456.25 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 | 1,345,825 | |
| -1 | 1,345,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 41 | 65 | 101 | 205 | 325 | 505 | 533 | 1,025 | 1,313 | 2,525 | 2,665 | 4,141 | 6,565 | 13,325 | 20,705 | 32,825 | 53,833 | 103,525 | 269,165 | 1,345,825 |
| -1 | -5 | -13 | -25 | -41 | -65 | -101 | -205 | -325 | -505 | -533 | -1,025 | -1,313 | -2,525 | -2,665 | -4,141 | -6,565 | -13,325 | -20,705 | -32,825 | -53,833 | -103,525 | -269,165 | -1,345,825 |
