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 3,681,545, 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 | 3,681,545 | |
| -1 | -3,681,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,681,545.
Example:
1 x 3,681,545 = 3,681,545
and
-1 x -3,681,545 = 3,681,545
Notice both answers equal 3,681,545
With that explanation out of the way, let's continue. Next, we take the number 3,681,545 and divide it by 2:
3,681,545 ÷ 2 = 1,840,772.5
If the quotient is a whole number, then 2 and 1,840,772.5 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 | 3,681,545 | |
| -1 | -3,681,545 |
Now, we try dividing 3,681,545 by 3:
3,681,545 ÷ 3 = 1,227,181.6667
If the quotient is a whole number, then 3 and 1,227,181.6667 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 | 3,681,545 | |
| -1 | -3,681,545 |
Let's try dividing by 4:
3,681,545 ÷ 4 = 920,386.25
If the quotient is a whole number, then 4 and 920,386.25 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 | 3,681,545 | |
| -1 | 3,681,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 293 | 359 | 1,465 | 1,795 | 2,051 | 2,513 | 10,255 | 12,565 | 105,187 | 525,935 | 736,309 | 3,681,545 |
| -1 | -5 | -7 | -35 | -293 | -359 | -1,465 | -1,795 | -2,051 | -2,513 | -10,255 | -12,565 | -105,187 | -525,935 | -736,309 | -3,681,545 |
