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 10,545,395, 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 | 10,545,395 | |
| -1 | -10,545,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,545,395.
Example:
1 x 10,545,395 = 10,545,395
and
-1 x -10,545,395 = 10,545,395
Notice both answers equal 10,545,395
With that explanation out of the way, let's continue. Next, we take the number 10,545,395 and divide it by 2:
10,545,395 ÷ 2 = 5,272,697.5
If the quotient is a whole number, then 2 and 5,272,697.5 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 | 10,545,395 | |
| -1 | -10,545,395 |
Now, we try dividing 10,545,395 by 3:
10,545,395 ÷ 3 = 3,515,131.6667
If the quotient is a whole number, then 3 and 3,515,131.6667 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 | 10,545,395 | |
| -1 | -10,545,395 |
Let's try dividing by 4:
10,545,395 ÷ 4 = 2,636,348.75
If the quotient is a whole number, then 4 and 2,636,348.75 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 | 10,545,395 | |
| -1 | 10,545,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 503 | 599 | 2,515 | 2,995 | 3,521 | 4,193 | 17,605 | 20,965 | 301,297 | 1,506,485 | 2,109,079 | 10,545,395 |
| -1 | -5 | -7 | -35 | -503 | -599 | -2,515 | -2,995 | -3,521 | -4,193 | -17,605 | -20,965 | -301,297 | -1,506,485 | -2,109,079 | -10,545,395 |
