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 5,401,253, 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 | 5,401,253 | |
| -1 | -5,401,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,401,253.
Example:
1 x 5,401,253 = 5,401,253
and
-1 x -5,401,253 = 5,401,253
Notice both answers equal 5,401,253
With that explanation out of the way, let's continue. Next, we take the number 5,401,253 and divide it by 2:
5,401,253 ÷ 2 = 2,700,626.5
If the quotient is a whole number, then 2 and 2,700,626.5 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 | 5,401,253 | |
| -1 | -5,401,253 |
Now, we try dividing 5,401,253 by 3:
5,401,253 ÷ 3 = 1,800,417.6667
If the quotient is a whole number, then 3 and 1,800,417.6667 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 | 5,401,253 | |
| -1 | -5,401,253 |
Let's try dividing by 4:
5,401,253 ÷ 4 = 1,350,313.25
If the quotient is a whole number, then 4 and 1,350,313.25 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 | 5,401,253 | |
| -1 | 5,401,253 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 107 | 143 | 353 | 1,177 | 1,391 | 3,883 | 4,589 | 15,301 | 37,771 | 50,479 | 415,481 | 491,023 | 5,401,253 |
| -1 | -11 | -13 | -107 | -143 | -353 | -1,177 | -1,391 | -3,883 | -4,589 | -15,301 | -37,771 | -50,479 | -415,481 | -491,023 | -5,401,253 |
