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 13,454,051, 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 | 13,454,051 | |
| -1 | -13,454,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,454,051.
Example:
1 x 13,454,051 = 13,454,051
and
-1 x -13,454,051 = 13,454,051
Notice both answers equal 13,454,051
With that explanation out of the way, let's continue. Next, we take the number 13,454,051 and divide it by 2:
13,454,051 ÷ 2 = 6,727,025.5
If the quotient is a whole number, then 2 and 6,727,025.5 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 | 13,454,051 | |
| -1 | -13,454,051 |
Now, we try dividing 13,454,051 by 3:
13,454,051 ÷ 3 = 4,484,683.6667
If the quotient is a whole number, then 3 and 4,484,683.6667 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 | 13,454,051 | |
| -1 | -13,454,051 |
Let's try dividing by 4:
13,454,051 ÷ 4 = 3,363,512.75
If the quotient is a whole number, then 4 and 3,363,512.75 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 | 13,454,051 | |
| -1 | 13,454,051 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 83 | 337 | 481 | 1,079 | 3,071 | 4,381 | 12,469 | 27,971 | 39,923 | 162,097 | 363,623 | 1,034,927 | 13,454,051 |
| -1 | -13 | -37 | -83 | -337 | -481 | -1,079 | -3,071 | -4,381 | -12,469 | -27,971 | -39,923 | -162,097 | -363,623 | -1,034,927 | -13,454,051 |
