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 3,162,523, 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 | 3,162,523 | |
| -1 | -3,162,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,162,523.
Example:
1 x 3,162,523 = 3,162,523
and
-1 x -3,162,523 = 3,162,523
Notice both answers equal 3,162,523
With that explanation out of the way, let's continue. Next, we take the number 3,162,523 and divide it by 2:
3,162,523 ÷ 2 = 1,581,261.5
If the quotient is a whole number, then 2 and 1,581,261.5 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 | 3,162,523 | |
| -1 | -3,162,523 |
Now, we try dividing 3,162,523 by 3:
3,162,523 ÷ 3 = 1,054,174.3333
If the quotient is a whole number, then 3 and 1,054,174.3333 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 | 3,162,523 | |
| -1 | -3,162,523 |
Let's try dividing by 4:
3,162,523 ÷ 4 = 790,630.75
If the quotient is a whole number, then 4 and 790,630.75 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 | 3,162,523 | |
| -1 | 3,162,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 161 | 299 | 1,511 | 2,093 | 10,577 | 19,643 | 34,753 | 137,501 | 243,271 | 451,789 | 3,162,523 |
| -1 | -7 | -13 | -23 | -91 | -161 | -299 | -1,511 | -2,093 | -10,577 | -19,643 | -34,753 | -137,501 | -243,271 | -451,789 | -3,162,523 |
