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 1,199,299, 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 | 1,199,299 | |
| -1 | -1,199,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,199,299.
Example:
1 x 1,199,299 = 1,199,299
and
-1 x -1,199,299 = 1,199,299
Notice both answers equal 1,199,299
With that explanation out of the way, let's continue. Next, we take the number 1,199,299 and divide it by 2:
1,199,299 ÷ 2 = 599,649.5
If the quotient is a whole number, then 2 and 599,649.5 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 | 1,199,299 | |
| -1 | -1,199,299 |
Now, we try dividing 1,199,299 by 3:
1,199,299 ÷ 3 = 399,766.3333
If the quotient is a whole number, then 3 and 399,766.3333 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 | 1,199,299 | |
| -1 | -1,199,299 |
Let's try dividing by 4:
1,199,299 ÷ 4 = 299,824.75
If the quotient is a whole number, then 4 and 299,824.75 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 | 1,199,299 | |
| -1 | 1,199,299 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 47 | 79 | 323 | 799 | 893 | 1,343 | 1,501 | 3,713 | 15,181 | 25,517 | 63,121 | 70,547 | 1,199,299 |
| -1 | -17 | -19 | -47 | -79 | -323 | -799 | -893 | -1,343 | -1,501 | -3,713 | -15,181 | -25,517 | -63,121 | -70,547 | -1,199,299 |
