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 13,876,445, 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 | 13,876,445 | |
| -1 | -13,876,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,876,445.
Example:
1 x 13,876,445 = 13,876,445
and
-1 x -13,876,445 = 13,876,445
Notice both answers equal 13,876,445
With that explanation out of the way, let's continue. Next, we take the number 13,876,445 and divide it by 2:
13,876,445 ÷ 2 = 6,938,222.5
If the quotient is a whole number, then 2 and 6,938,222.5 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 | 13,876,445 | |
| -1 | -13,876,445 |
Now, we try dividing 13,876,445 by 3:
13,876,445 ÷ 3 = 4,625,481.6667
If the quotient is a whole number, then 3 and 4,625,481.6667 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 | 13,876,445 | |
| -1 | -13,876,445 |
Let's try dividing by 4:
13,876,445 ÷ 4 = 3,469,111.25
If the quotient is a whole number, then 4 and 3,469,111.25 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 | 13,876,445 | |
| -1 | 13,876,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 157 | 785 | 1,607 | 1,727 | 8,035 | 8,635 | 17,677 | 88,385 | 252,299 | 1,261,495 | 2,775,289 | 13,876,445 |
| -1 | -5 | -11 | -55 | -157 | -785 | -1,607 | -1,727 | -8,035 | -8,635 | -17,677 | -88,385 | -252,299 | -1,261,495 | -2,775,289 | -13,876,445 |
