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 1,198,769, 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 | 1,198,769 | |
| -1 | -1,198,769 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,198,769.
Example:
1 x 1,198,769 = 1,198,769
and
-1 x -1,198,769 = 1,198,769
Notice both answers equal 1,198,769
With that explanation out of the way, let's continue. Next, we take the number 1,198,769 and divide it by 2:
1,198,769 ÷ 2 = 599,384.5
If the quotient is a whole number, then 2 and 599,384.5 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 | 1,198,769 | |
| -1 | -1,198,769 |
Now, we try dividing 1,198,769 by 3:
1,198,769 ÷ 3 = 399,589.6667
If the quotient is a whole number, then 3 and 399,589.6667 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 | 1,198,769 | |
| -1 | -1,198,769 |
Let's try dividing by 4:
1,198,769 ÷ 4 = 299,692.25
If the quotient is a whole number, then 4 and 299,692.25 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 | 1,198,769 | |
| -1 | 1,198,769 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 83 | 101 | 143 | 913 | 1,079 | 1,111 | 1,313 | 8,383 | 11,869 | 14,443 | 92,213 | 108,979 | 1,198,769 |
| -1 | -11 | -13 | -83 | -101 | -143 | -913 | -1,079 | -1,111 | -1,313 | -8,383 | -11,869 | -14,443 | -92,213 | -108,979 | -1,198,769 |
