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 1,241,045, 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 | 1,241,045 | |
| -1 | -1,241,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,241,045.
Example:
1 x 1,241,045 = 1,241,045
and
-1 x -1,241,045 = 1,241,045
Notice both answers equal 1,241,045
With that explanation out of the way, let's continue. Next, we take the number 1,241,045 and divide it by 2:
1,241,045 ÷ 2 = 620,522.5
If the quotient is a whole number, then 2 and 620,522.5 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 | 1,241,045 | |
| -1 | -1,241,045 |
Now, we try dividing 1,241,045 by 3:
1,241,045 ÷ 3 = 413,681.6667
If the quotient is a whole number, then 3 and 413,681.6667 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 | 1,241,045 | |
| -1 | -1,241,045 |
Let's try dividing by 4:
1,241,045 ÷ 4 = 310,261.25
If the quotient is a whole number, then 4 and 310,261.25 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 | 1,241,045 | |
| -1 | 1,241,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 313 | 793 | 1,565 | 3,965 | 4,069 | 19,093 | 20,345 | 95,465 | 248,209 | 1,241,045 |
| -1 | -5 | -13 | -61 | -65 | -305 | -313 | -793 | -1,565 | -3,965 | -4,069 | -19,093 | -20,345 | -95,465 | -248,209 | -1,241,045 |
