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 4,298,203, 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 | 4,298,203 | |
| -1 | -4,298,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,298,203.
Example:
1 x 4,298,203 = 4,298,203
and
-1 x -4,298,203 = 4,298,203
Notice both answers equal 4,298,203
With that explanation out of the way, let's continue. Next, we take the number 4,298,203 and divide it by 2:
4,298,203 ÷ 2 = 2,149,101.5
If the quotient is a whole number, then 2 and 2,149,101.5 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 | 4,298,203 | |
| -1 | -4,298,203 |
Now, we try dividing 4,298,203 by 3:
4,298,203 ÷ 3 = 1,432,734.3333
If the quotient is a whole number, then 3 and 1,432,734.3333 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 | 4,298,203 | |
| -1 | -4,298,203 |
Let's try dividing by 4:
4,298,203 ÷ 4 = 1,074,550.75
If the quotient is a whole number, then 4 and 1,074,550.75 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 | 4,298,203 | |
| -1 | 4,298,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 149 | 317 | 1,043 | 1,937 | 2,219 | 4,121 | 13,559 | 28,847 | 47,233 | 330,631 | 614,029 | 4,298,203 |
| -1 | -7 | -13 | -91 | -149 | -317 | -1,043 | -1,937 | -2,219 | -4,121 | -13,559 | -28,847 | -47,233 | -330,631 | -614,029 | -4,298,203 |
