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 3,561,125, 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 | 3,561,125 | |
| -1 | -3,561,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,561,125.
Example:
1 x 3,561,125 = 3,561,125
and
-1 x -3,561,125 = 3,561,125
Notice both answers equal 3,561,125
With that explanation out of the way, let's continue. Next, we take the number 3,561,125 and divide it by 2:
3,561,125 ÷ 2 = 1,780,562.5
If the quotient is a whole number, then 2 and 1,780,562.5 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 | 3,561,125 | |
| -1 | -3,561,125 |
Now, we try dividing 3,561,125 by 3:
3,561,125 ÷ 3 = 1,187,041.6667
If the quotient is a whole number, then 3 and 1,187,041.6667 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 | 3,561,125 | |
| -1 | -3,561,125 |
Let's try dividing by 4:
3,561,125 ÷ 4 = 890,281.25
If the quotient is a whole number, then 4 and 890,281.25 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 | 3,561,125 | |
| -1 | 3,561,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 125 | 155 | 775 | 919 | 3,875 | 4,595 | 22,975 | 28,489 | 114,875 | 142,445 | 712,225 | 3,561,125 |
| -1 | -5 | -25 | -31 | -125 | -155 | -775 | -919 | -3,875 | -4,595 | -22,975 | -28,489 | -114,875 | -142,445 | -712,225 | -3,561,125 |
