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 13,726,025, 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 | 13,726,025 | |
| -1 | -13,726,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,726,025.
Example:
1 x 13,726,025 = 13,726,025
and
-1 x -13,726,025 = 13,726,025
Notice both answers equal 13,726,025
With that explanation out of the way, let's continue. Next, we take the number 13,726,025 and divide it by 2:
13,726,025 ÷ 2 = 6,863,012.5
If the quotient is a whole number, then 2 and 6,863,012.5 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 | 13,726,025 | |
| -1 | -13,726,025 |
Now, we try dividing 13,726,025 by 3:
13,726,025 ÷ 3 = 4,575,341.6667
If the quotient is a whole number, then 3 and 4,575,341.6667 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 | 13,726,025 | |
| -1 | -13,726,025 |
Let's try dividing by 4:
13,726,025 ÷ 4 = 3,431,506.25
If the quotient is a whole number, then 4 and 3,431,506.25 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 | 13,726,025 | |
| -1 | 13,726,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 89 | 155 | 199 | 445 | 775 | 995 | 2,225 | 2,759 | 4,975 | 6,169 | 13,795 | 17,711 | 30,845 | 68,975 | 88,555 | 154,225 | 442,775 | 549,041 | 2,745,205 | 13,726,025 |
| -1 | -5 | -25 | -31 | -89 | -155 | -199 | -445 | -775 | -995 | -2,225 | -2,759 | -4,975 | -6,169 | -13,795 | -17,711 | -30,845 | -68,975 | -88,555 | -154,225 | -442,775 | -549,041 | -2,745,205 | -13,726,025 |
