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 12,455,051, 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 | 12,455,051 | |
| -1 | -12,455,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,455,051.
Example:
1 x 12,455,051 = 12,455,051
and
-1 x -12,455,051 = 12,455,051
Notice both answers equal 12,455,051
With that explanation out of the way, let's continue. Next, we take the number 12,455,051 and divide it by 2:
12,455,051 ÷ 2 = 6,227,525.5
If the quotient is a whole number, then 2 and 6,227,525.5 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 | 12,455,051 | |
| -1 | -12,455,051 |
Now, we try dividing 12,455,051 by 3:
12,455,051 ÷ 3 = 4,151,683.6667
If the quotient is a whole number, then 3 and 4,151,683.6667 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 | 12,455,051 | |
| -1 | -12,455,051 |
Let's try dividing by 4:
12,455,051 ÷ 4 = 3,113,762.75
If the quotient is a whole number, then 4 and 3,113,762.75 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 | 12,455,051 | |
| -1 | 12,455,051 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 2,531 | 4,921 | 17,717 | 48,089 | 93,647 | 336,623 | 655,529 | 1,779,293 | 12,455,051 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -2,531 | -4,921 | -17,717 | -48,089 | -93,647 | -336,623 | -655,529 | -1,779,293 | -12,455,051 |
