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 1,432,981, 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 | 1,432,981 | |
| -1 | -1,432,981 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,432,981.
Example:
1 x 1,432,981 = 1,432,981
and
-1 x -1,432,981 = 1,432,981
Notice both answers equal 1,432,981
With that explanation out of the way, let's continue. Next, we take the number 1,432,981 and divide it by 2:
1,432,981 ÷ 2 = 716,490.5
If the quotient is a whole number, then 2 and 716,490.5 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 | 1,432,981 | |
| -1 | -1,432,981 |
Now, we try dividing 1,432,981 by 3:
1,432,981 ÷ 3 = 477,660.3333
If the quotient is a whole number, then 3 and 477,660.3333 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 | 1,432,981 | |
| -1 | -1,432,981 |
Let's try dividing by 4:
1,432,981 ÷ 4 = 358,245.25
If the quotient is a whole number, then 4 and 358,245.25 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 | 1,432,981 | |
| -1 | 1,432,981 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 79 | 97 | 187 | 869 | 1,067 | 1,343 | 1,649 | 7,663 | 14,773 | 18,139 | 84,293 | 130,271 | 1,432,981 |
| -1 | -11 | -17 | -79 | -97 | -187 | -869 | -1,067 | -1,343 | -1,649 | -7,663 | -14,773 | -18,139 | -84,293 | -130,271 | -1,432,981 |
