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 4,451,161, 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 | 4,451,161 | |
| -1 | -4,451,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,451,161.
Example:
1 x 4,451,161 = 4,451,161
and
-1 x -4,451,161 = 4,451,161
Notice both answers equal 4,451,161
With that explanation out of the way, let's continue. Next, we take the number 4,451,161 and divide it by 2:
4,451,161 ÷ 2 = 2,225,580.5
If the quotient is a whole number, then 2 and 2,225,580.5 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 | 4,451,161 | |
| -1 | -4,451,161 |
Now, we try dividing 4,451,161 by 3:
4,451,161 ÷ 3 = 1,483,720.3333
If the quotient is a whole number, then 3 and 1,483,720.3333 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 | 4,451,161 | |
| -1 | -4,451,161 |
Let's try dividing by 4:
4,451,161 ÷ 4 = 1,112,790.25
If the quotient is a whole number, then 4 and 1,112,790.25 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 | 4,451,161 | |
| -1 | 4,451,161 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 1,831 | 2,431 | 20,141 | 23,803 | 31,127 | 261,833 | 342,397 | 404,651 | 4,451,161 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -1,831 | -2,431 | -20,141 | -23,803 | -31,127 | -261,833 | -342,397 | -404,651 | -4,451,161 |
