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 5,355,251, 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 | 5,355,251 | |
| -1 | -5,355,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,355,251.
Example:
1 x 5,355,251 = 5,355,251
and
-1 x -5,355,251 = 5,355,251
Notice both answers equal 5,355,251
With that explanation out of the way, let's continue. Next, we take the number 5,355,251 and divide it by 2:
5,355,251 ÷ 2 = 2,677,625.5
If the quotient is a whole number, then 2 and 2,677,625.5 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 | 5,355,251 | |
| -1 | -5,355,251 |
Now, we try dividing 5,355,251 by 3:
5,355,251 ÷ 3 = 1,785,083.6667
If the quotient is a whole number, then 3 and 1,785,083.6667 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 | 5,355,251 | |
| -1 | -5,355,251 |
Let's try dividing by 4:
5,355,251 ÷ 4 = 1,338,812.75
If the quotient is a whole number, then 4 and 1,338,812.75 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 | 5,355,251 | |
| -1 | 5,355,251 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 61 | 253 | 347 | 671 | 1,403 | 3,817 | 7,981 | 15,433 | 21,167 | 87,791 | 232,837 | 486,841 | 5,355,251 |
| -1 | -11 | -23 | -61 | -253 | -347 | -671 | -1,403 | -3,817 | -7,981 | -15,433 | -21,167 | -87,791 | -232,837 | -486,841 | -5,355,251 |
