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 1,150,471, 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 | 1,150,471 | |
| -1 | -1,150,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,150,471.
Example:
1 x 1,150,471 = 1,150,471
and
-1 x -1,150,471 = 1,150,471
Notice both answers equal 1,150,471
With that explanation out of the way, let's continue. Next, we take the number 1,150,471 and divide it by 2:
1,150,471 ÷ 2 = 575,235.5
If the quotient is a whole number, then 2 and 575,235.5 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 | 1,150,471 | |
| -1 | -1,150,471 |
Now, we try dividing 1,150,471 by 3:
1,150,471 ÷ 3 = 383,490.3333
If the quotient is a whole number, then 3 and 383,490.3333 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 | 1,150,471 | |
| -1 | -1,150,471 |
Let's try dividing by 4:
1,150,471 ÷ 4 = 287,617.75
If the quotient is a whole number, then 4 and 287,617.75 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 | 1,150,471 | |
| -1 | 1,150,471 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 53 | 371 | 443 | 2,597 | 3,101 | 21,707 | 23,479 | 164,353 | 1,150,471 |
| -1 | -7 | -49 | -53 | -371 | -443 | -2,597 | -3,101 | -21,707 | -23,479 | -164,353 | -1,150,471 |
