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 5,113,381, 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 | 5,113,381 | |
| -1 | -5,113,381 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,113,381.
Example:
1 x 5,113,381 = 5,113,381
and
-1 x -5,113,381 = 5,113,381
Notice both answers equal 5,113,381
With that explanation out of the way, let's continue. Next, we take the number 5,113,381 and divide it by 2:
5,113,381 ÷ 2 = 2,556,690.5
If the quotient is a whole number, then 2 and 2,556,690.5 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 | 5,113,381 | |
| -1 | -5,113,381 |
Now, we try dividing 5,113,381 by 3:
5,113,381 ÷ 3 = 1,704,460.3333
If the quotient is a whole number, then 3 and 1,704,460.3333 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 | 5,113,381 | |
| -1 | -5,113,381 |
Let's try dividing by 4:
5,113,381 ÷ 4 = 1,278,345.25
If the quotient is a whole number, then 4 and 1,278,345.25 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 | 5,113,381 | |
| -1 | 5,113,381 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 83 | 91 | 581 | 677 | 1,079 | 4,739 | 7,553 | 8,801 | 56,191 | 61,607 | 393,337 | 730,483 | 5,113,381 |
| -1 | -7 | -13 | -83 | -91 | -581 | -677 | -1,079 | -4,739 | -7,553 | -8,801 | -56,191 | -61,607 | -393,337 | -730,483 | -5,113,381 |
