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 4,322,155, 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 | 4,322,155 | |
| -1 | -4,322,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,322,155.
Example:
1 x 4,322,155 = 4,322,155
and
-1 x -4,322,155 = 4,322,155
Notice both answers equal 4,322,155
With that explanation out of the way, let's continue. Next, we take the number 4,322,155 and divide it by 2:
4,322,155 ÷ 2 = 2,161,077.5
If the quotient is a whole number, then 2 and 2,161,077.5 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 | 4,322,155 | |
| -1 | -4,322,155 |
Now, we try dividing 4,322,155 by 3:
4,322,155 ÷ 3 = 1,440,718.3333
If the quotient is a whole number, then 3 and 1,440,718.3333 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 | 4,322,155 | |
| -1 | -4,322,155 |
Let's try dividing by 4:
4,322,155 ÷ 4 = 1,080,538.75
If the quotient is a whole number, then 4 and 1,080,538.75 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 | 4,322,155 | |
| -1 | 4,322,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 61 | 185 | 305 | 383 | 1,915 | 2,257 | 11,285 | 14,171 | 23,363 | 70,855 | 116,815 | 864,431 | 4,322,155 |
| -1 | -5 | -37 | -61 | -185 | -305 | -383 | -1,915 | -2,257 | -11,285 | -14,171 | -23,363 | -70,855 | -116,815 | -864,431 | -4,322,155 |
