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 40,350,013, 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 | 40,350,013 | |
| -1 | -40,350,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,350,013.
Example:
1 x 40,350,013 = 40,350,013
and
-1 x -40,350,013 = 40,350,013
Notice both answers equal 40,350,013
With that explanation out of the way, let's continue. Next, we take the number 40,350,013 and divide it by 2:
40,350,013 ÷ 2 = 20,175,006.5
If the quotient is a whole number, then 2 and 20,175,006.5 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 | 40,350,013 | |
| -1 | -40,350,013 |
Now, we try dividing 40,350,013 by 3:
40,350,013 ÷ 3 = 13,450,004.3333
If the quotient is a whole number, then 3 and 13,450,004.3333 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 | 40,350,013 | |
| -1 | -40,350,013 |
Let's try dividing by 4:
40,350,013 ÷ 4 = 10,087,503.25
If the quotient is a whole number, then 4 and 10,087,503.25 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 | 40,350,013 | |
| -1 | 40,350,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 67 | 583 | 737 | 1,033 | 3,551 | 11,363 | 39,061 | 54,749 | 69,211 | 602,239 | 761,321 | 3,668,183 | 40,350,013 |
| -1 | -11 | -53 | -67 | -583 | -737 | -1,033 | -3,551 | -11,363 | -39,061 | -54,749 | -69,211 | -602,239 | -761,321 | -3,668,183 | -40,350,013 |
