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 10,506,605, 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 | 10,506,605 | |
| -1 | -10,506,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,506,605.
Example:
1 x 10,506,605 = 10,506,605
and
-1 x -10,506,605 = 10,506,605
Notice both answers equal 10,506,605
With that explanation out of the way, let's continue. Next, we take the number 10,506,605 and divide it by 2:
10,506,605 ÷ 2 = 5,253,302.5
If the quotient is a whole number, then 2 and 5,253,302.5 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 | 10,506,605 | |
| -1 | -10,506,605 |
Now, we try dividing 10,506,605 by 3:
10,506,605 ÷ 3 = 3,502,201.6667
If the quotient is a whole number, then 3 and 3,502,201.6667 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 | 10,506,605 | |
| -1 | -10,506,605 |
Let's try dividing by 4:
10,506,605 ÷ 4 = 2,626,651.25
If the quotient is a whole number, then 4 and 2,626,651.25 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 | 10,506,605 | |
| -1 | 10,506,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 79 | 335 | 395 | 397 | 1,985 | 5,293 | 26,465 | 26,599 | 31,363 | 132,995 | 156,815 | 2,101,321 | 10,506,605 |
| -1 | -5 | -67 | -79 | -335 | -395 | -397 | -1,985 | -5,293 | -26,465 | -26,599 | -31,363 | -132,995 | -156,815 | -2,101,321 | -10,506,605 |
