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 4,122,349, 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 | 4,122,349 | |
| -1 | -4,122,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,122,349.
Example:
1 x 4,122,349 = 4,122,349
and
-1 x -4,122,349 = 4,122,349
Notice both answers equal 4,122,349
With that explanation out of the way, let's continue. Next, we take the number 4,122,349 and divide it by 2:
4,122,349 ÷ 2 = 2,061,174.5
If the quotient is a whole number, then 2 and 2,061,174.5 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 | 4,122,349 | |
| -1 | -4,122,349 |
Now, we try dividing 4,122,349 by 3:
4,122,349 ÷ 3 = 1,374,116.3333
If the quotient is a whole number, then 3 and 1,374,116.3333 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 | 4,122,349 | |
| -1 | -4,122,349 |
Let's try dividing by 4:
4,122,349 ÷ 4 = 1,030,587.25
If the quotient is a whole number, then 4 and 1,030,587.25 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 | 4,122,349 | |
| -1 | 4,122,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 121 | 157 | 217 | 341 | 847 | 1,099 | 1,727 | 2,387 | 3,751 | 4,867 | 12,089 | 18,997 | 26,257 | 34,069 | 53,537 | 132,979 | 374,759 | 588,907 | 4,122,349 |
| -1 | -7 | -11 | -31 | -77 | -121 | -157 | -217 | -341 | -847 | -1,099 | -1,727 | -2,387 | -3,751 | -4,867 | -12,089 | -18,997 | -26,257 | -34,069 | -53,537 | -132,979 | -374,759 | -588,907 | -4,122,349 |
