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 3,156,725, 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 | 3,156,725 | |
| -1 | -3,156,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,156,725.
Example:
1 x 3,156,725 = 3,156,725
and
-1 x -3,156,725 = 3,156,725
Notice both answers equal 3,156,725
With that explanation out of the way, let's continue. Next, we take the number 3,156,725 and divide it by 2:
3,156,725 ÷ 2 = 1,578,362.5
If the quotient is a whole number, then 2 and 1,578,362.5 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 | 3,156,725 | |
| -1 | -3,156,725 |
Now, we try dividing 3,156,725 by 3:
3,156,725 ÷ 3 = 1,052,241.6667
If the quotient is a whole number, then 3 and 1,052,241.6667 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 | 3,156,725 | |
| -1 | -3,156,725 |
Let's try dividing by 4:
3,156,725 ÷ 4 = 789,181.25
If the quotient is a whole number, then 4 and 789,181.25 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 | 3,156,725 | |
| -1 | 3,156,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 883 | 3,575 | 4,415 | 9,713 | 11,479 | 22,075 | 48,565 | 57,395 | 126,269 | 242,825 | 286,975 | 631,345 | 3,156,725 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -883 | -3,575 | -4,415 | -9,713 | -11,479 | -22,075 | -48,565 | -57,395 | -126,269 | -242,825 | -286,975 | -631,345 | -3,156,725 |
