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 7,105,045, 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 | 7,105,045 | |
| -1 | -7,105,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,105,045.
Example:
1 x 7,105,045 = 7,105,045
and
-1 x -7,105,045 = 7,105,045
Notice both answers equal 7,105,045
With that explanation out of the way, let's continue. Next, we take the number 7,105,045 and divide it by 2:
7,105,045 ÷ 2 = 3,552,522.5
If the quotient is a whole number, then 2 and 3,552,522.5 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 | 7,105,045 | |
| -1 | -7,105,045 |
Now, we try dividing 7,105,045 by 3:
7,105,045 ÷ 3 = 2,368,348.3333
If the quotient is a whole number, then 3 and 2,368,348.3333 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 | 7,105,045 | |
| -1 | -7,105,045 |
Let's try dividing by 4:
7,105,045 ÷ 4 = 1,776,261.25
If the quotient is a whole number, then 4 and 1,776,261.25 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 | 7,105,045 | |
| -1 | 7,105,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 31 | 115 | 155 | 713 | 1,993 | 3,565 | 9,965 | 45,839 | 61,783 | 229,195 | 308,915 | 1,421,009 | 7,105,045 |
| -1 | -5 | -23 | -31 | -115 | -155 | -713 | -1,993 | -3,565 | -9,965 | -45,839 | -61,783 | -229,195 | -308,915 | -1,421,009 | -7,105,045 |
