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 13,790,051, 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 | 13,790,051 | |
| -1 | -13,790,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,790,051.
Example:
1 x 13,790,051 = 13,790,051
and
-1 x -13,790,051 = 13,790,051
Notice both answers equal 13,790,051
With that explanation out of the way, let's continue. Next, we take the number 13,790,051 and divide it by 2:
13,790,051 ÷ 2 = 6,895,025.5
If the quotient is a whole number, then 2 and 6,895,025.5 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 | 13,790,051 | |
| -1 | -13,790,051 |
Now, we try dividing 13,790,051 by 3:
13,790,051 ÷ 3 = 4,596,683.6667
If the quotient is a whole number, then 3 and 4,596,683.6667 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 | 13,790,051 | |
| -1 | -13,790,051 |
Let's try dividing by 4:
13,790,051 ÷ 4 = 3,447,512.75
If the quotient is a whole number, then 4 and 3,447,512.75 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 | 13,790,051 | |
| -1 | 13,790,051 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 139 | 311 | 319 | 1,529 | 3,421 | 4,031 | 9,019 | 43,229 | 44,341 | 99,209 | 475,519 | 1,253,641 | 13,790,051 |
| -1 | -11 | -29 | -139 | -311 | -319 | -1,529 | -3,421 | -4,031 | -9,019 | -43,229 | -44,341 | -99,209 | -475,519 | -1,253,641 | -13,790,051 |
