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 37,425,713, 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 | 37,425,713 | |
| -1 | -37,425,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,425,713.
Example:
1 x 37,425,713 = 37,425,713
and
-1 x -37,425,713 = 37,425,713
Notice both answers equal 37,425,713
With that explanation out of the way, let's continue. Next, we take the number 37,425,713 and divide it by 2:
37,425,713 ÷ 2 = 18,712,856.5
If the quotient is a whole number, then 2 and 18,712,856.5 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 | 37,425,713 | |
| -1 | -37,425,713 |
Now, we try dividing 37,425,713 by 3:
37,425,713 ÷ 3 = 12,475,237.6667
If the quotient is a whole number, then 3 and 12,475,237.6667 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 | 37,425,713 | |
| -1 | -37,425,713 |
Let's try dividing by 4:
37,425,713 ÷ 4 = 9,356,428.25
If the quotient is a whole number, then 4 and 9,356,428.25 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 | 37,425,713 | |
| -1 | 37,425,713 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 113 | 349 | 949 | 1,469 | 4,537 | 8,249 | 25,477 | 39,437 | 107,237 | 331,201 | 512,681 | 2,878,901 | 37,425,713 |
| -1 | -13 | -73 | -113 | -349 | -949 | -1,469 | -4,537 | -8,249 | -25,477 | -39,437 | -107,237 | -331,201 | -512,681 | -2,878,901 | -37,425,713 |
