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 4,487,315, 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 | 4,487,315 | |
| -1 | -4,487,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,487,315.
Example:
1 x 4,487,315 = 4,487,315
and
-1 x -4,487,315 = 4,487,315
Notice both answers equal 4,487,315
With that explanation out of the way, let's continue. Next, we take the number 4,487,315 and divide it by 2:
4,487,315 ÷ 2 = 2,243,657.5
If the quotient is a whole number, then 2 and 2,243,657.5 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 | 4,487,315 | |
| -1 | -4,487,315 |
Now, we try dividing 4,487,315 by 3:
4,487,315 ÷ 3 = 1,495,771.6667
If the quotient is a whole number, then 3 and 1,495,771.6667 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 | 4,487,315 | |
| -1 | -4,487,315 |
Let's try dividing by 4:
4,487,315 ÷ 4 = 1,121,828.75
If the quotient is a whole number, then 4 and 1,121,828.75 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 | 4,487,315 | |
| -1 | 4,487,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 4,421 | 22,105 | 30,947 | 128,209 | 154,735 | 641,045 | 897,463 | 4,487,315 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -4,421 | -22,105 | -30,947 | -128,209 | -154,735 | -641,045 | -897,463 | -4,487,315 |
