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 4,292,981, 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 | 4,292,981 | |
| -1 | -4,292,981 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,292,981.
Example:
1 x 4,292,981 = 4,292,981
and
-1 x -4,292,981 = 4,292,981
Notice both answers equal 4,292,981
With that explanation out of the way, let's continue. Next, we take the number 4,292,981 and divide it by 2:
4,292,981 ÷ 2 = 2,146,490.5
If the quotient is a whole number, then 2 and 2,146,490.5 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 | 4,292,981 | |
| -1 | -4,292,981 |
Now, we try dividing 4,292,981 by 3:
4,292,981 ÷ 3 = 1,430,993.6667
If the quotient is a whole number, then 3 and 1,430,993.6667 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 | 4,292,981 | |
| -1 | -4,292,981 |
Let's try dividing by 4:
4,292,981 ÷ 4 = 1,073,245.25
If the quotient is a whole number, then 4 and 1,073,245.25 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 | 4,292,981 | |
| -1 | 4,292,981 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 439 | 889 | 1,397 | 3,073 | 4,829 | 9,779 | 33,803 | 55,753 | 390,271 | 613,283 | 4,292,981 |
| -1 | -7 | -11 | -77 | -127 | -439 | -889 | -1,397 | -3,073 | -4,829 | -9,779 | -33,803 | -55,753 | -390,271 | -613,283 | -4,292,981 |
