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 1,199,261, 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 | 1,199,261 | |
| -1 | -1,199,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,199,261.
Example:
1 x 1,199,261 = 1,199,261
and
-1 x -1,199,261 = 1,199,261
Notice both answers equal 1,199,261
With that explanation out of the way, let's continue. Next, we take the number 1,199,261 and divide it by 2:
1,199,261 ÷ 2 = 599,630.5
If the quotient is a whole number, then 2 and 599,630.5 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 | 1,199,261 | |
| -1 | -1,199,261 |
Now, we try dividing 1,199,261 by 3:
1,199,261 ÷ 3 = 399,753.6667
If the quotient is a whole number, then 3 and 399,753.6667 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 | 1,199,261 | |
| -1 | -1,199,261 |
Let's try dividing by 4:
1,199,261 ÷ 4 = 299,815.25
If the quotient is a whole number, then 4 and 299,815.25 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 | 1,199,261 | |
| -1 | 1,199,261 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 71 | 127 | 133 | 497 | 889 | 1,349 | 2,413 | 9,017 | 9,443 | 16,891 | 63,119 | 171,323 | 1,199,261 |
| -1 | -7 | -19 | -71 | -127 | -133 | -497 | -889 | -1,349 | -2,413 | -9,017 | -9,443 | -16,891 | -63,119 | -171,323 | -1,199,261 |
