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 37,731,683, 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 | 37,731,683 | |
| -1 | -37,731,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,731,683.
Example:
1 x 37,731,683 = 37,731,683
and
-1 x -37,731,683 = 37,731,683
Notice both answers equal 37,731,683
With that explanation out of the way, let's continue. Next, we take the number 37,731,683 and divide it by 2:
37,731,683 ÷ 2 = 18,865,841.5
If the quotient is a whole number, then 2 and 18,865,841.5 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 | 37,731,683 | |
| -1 | -37,731,683 |
Now, we try dividing 37,731,683 by 3:
37,731,683 ÷ 3 = 12,577,227.6667
If the quotient is a whole number, then 3 and 12,577,227.6667 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 | 37,731,683 | |
| -1 | -37,731,683 |
Let's try dividing by 4:
37,731,683 ÷ 4 = 9,432,920.75
If the quotient is a whole number, then 4 and 9,432,920.75 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 | 37,731,683 | |
| -1 | 37,731,683 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 241 | 331 | 473 | 2,651 | 3,641 | 10,363 | 14,233 | 79,771 | 113,993 | 156,563 | 877,481 | 3,430,153 | 37,731,683 |
| -1 | -11 | -43 | -241 | -331 | -473 | -2,651 | -3,641 | -10,363 | -14,233 | -79,771 | -113,993 | -156,563 | -877,481 | -3,430,153 | -37,731,683 |
