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 1,129,051, 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 | 1,129,051 | |
| -1 | -1,129,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,129,051.
Example:
1 x 1,129,051 = 1,129,051
and
-1 x -1,129,051 = 1,129,051
Notice both answers equal 1,129,051
With that explanation out of the way, let's continue. Next, we take the number 1,129,051 and divide it by 2:
1,129,051 ÷ 2 = 564,525.5
If the quotient is a whole number, then 2 and 564,525.5 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 | 1,129,051 | |
| -1 | -1,129,051 |
Now, we try dividing 1,129,051 by 3:
1,129,051 ÷ 3 = 376,350.3333
If the quotient is a whole number, then 3 and 376,350.3333 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 | 1,129,051 | |
| -1 | -1,129,051 |
Let's try dividing by 4:
1,129,051 ÷ 4 = 282,262.75
If the quotient is a whole number, then 4 and 282,262.75 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 | 1,129,051 | |
| -1 | 1,129,051 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 43 | 77 | 121 | 217 | 301 | 341 | 473 | 847 | 1,333 | 2,387 | 3,311 | 3,751 | 5,203 | 9,331 | 14,663 | 26,257 | 36,421 | 102,641 | 161,293 | 1,129,051 |
| -1 | -7 | -11 | -31 | -43 | -77 | -121 | -217 | -301 | -341 | -473 | -847 | -1,333 | -2,387 | -3,311 | -3,751 | -5,203 | -9,331 | -14,663 | -26,257 | -36,421 | -102,641 | -161,293 | -1,129,051 |
