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 37,598,813, 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 | 37,598,813 | |
| -1 | -37,598,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,598,813.
Example:
1 x 37,598,813 = 37,598,813
and
-1 x -37,598,813 = 37,598,813
Notice both answers equal 37,598,813
With that explanation out of the way, let's continue. Next, we take the number 37,598,813 and divide it by 2:
37,598,813 ÷ 2 = 18,799,406.5
If the quotient is a whole number, then 2 and 18,799,406.5 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 | 37,598,813 | |
| -1 | -37,598,813 |
Now, we try dividing 37,598,813 by 3:
37,598,813 ÷ 3 = 12,532,937.6667
If the quotient is a whole number, then 3 and 12,532,937.6667 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 | 37,598,813 | |
| -1 | -37,598,813 |
Let's try dividing by 4:
37,598,813 ÷ 4 = 9,399,703.25
If the quotient is a whole number, then 4 and 9,399,703.25 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 | 37,598,813 | |
| -1 | 37,598,813 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 161 | 301 | 989 | 5,431 | 6,923 | 38,017 | 124,913 | 233,533 | 874,391 | 1,634,731 | 5,371,259 | 37,598,813 |
| -1 | -7 | -23 | -43 | -161 | -301 | -989 | -5,431 | -6,923 | -38,017 | -124,913 | -233,533 | -874,391 | -1,634,731 | -5,371,259 | -37,598,813 |
