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 40,374,373, 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 | 40,374,373 | |
| -1 | -40,374,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,374,373.
Example:
1 x 40,374,373 = 40,374,373
and
-1 x -40,374,373 = 40,374,373
Notice both answers equal 40,374,373
With that explanation out of the way, let's continue. Next, we take the number 40,374,373 and divide it by 2:
40,374,373 ÷ 2 = 20,187,186.5
If the quotient is a whole number, then 2 and 20,187,186.5 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 | 40,374,373 | |
| -1 | -40,374,373 |
Now, we try dividing 40,374,373 by 3:
40,374,373 ÷ 3 = 13,458,124.3333
If the quotient is a whole number, then 3 and 13,458,124.3333 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 | 40,374,373 | |
| -1 | -40,374,373 |
Let's try dividing by 4:
40,374,373 ÷ 4 = 10,093,593.25
If the quotient is a whole number, then 4 and 10,093,593.25 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 | 40,374,373 | |
| -1 | 40,374,373 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 223 | 247 | 733 | 2,899 | 4,237 | 9,529 | 13,927 | 55,081 | 163,459 | 181,051 | 2,124,967 | 3,105,721 | 40,374,373 |
| -1 | -13 | -19 | -223 | -247 | -733 | -2,899 | -4,237 | -9,529 | -13,927 | -55,081 | -163,459 | -181,051 | -2,124,967 | -3,105,721 | -40,374,373 |
