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 5,087,225, 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 | 5,087,225 | |
| -1 | -5,087,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,087,225.
Example:
1 x 5,087,225 = 5,087,225
and
-1 x -5,087,225 = 5,087,225
Notice both answers equal 5,087,225
With that explanation out of the way, let's continue. Next, we take the number 5,087,225 and divide it by 2:
5,087,225 ÷ 2 = 2,543,612.5
If the quotient is a whole number, then 2 and 2,543,612.5 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 | 5,087,225 | |
| -1 | -5,087,225 |
Now, we try dividing 5,087,225 by 3:
5,087,225 ÷ 3 = 1,695,741.6667
If the quotient is a whole number, then 3 and 1,695,741.6667 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 | 5,087,225 | |
| -1 | -5,087,225 |
Let's try dividing by 4:
5,087,225 ÷ 4 = 1,271,806.25
If the quotient is a whole number, then 4 and 1,271,806.25 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 | 5,087,225 | |
| -1 | 5,087,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 715 | 1,423 | 3,575 | 7,115 | 15,653 | 18,499 | 35,575 | 78,265 | 92,495 | 203,489 | 391,325 | 462,475 | 1,017,445 | 5,087,225 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -715 | -1,423 | -3,575 | -7,115 | -15,653 | -18,499 | -35,575 | -78,265 | -92,495 | -203,489 | -391,325 | -462,475 | -1,017,445 | -5,087,225 |
