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 38,606,737, 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 | 38,606,737 | |
| -1 | -38,606,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,606,737.
Example:
1 x 38,606,737 = 38,606,737
and
-1 x -38,606,737 = 38,606,737
Notice both answers equal 38,606,737
With that explanation out of the way, let's continue. Next, we take the number 38,606,737 and divide it by 2:
38,606,737 ÷ 2 = 19,303,368.5
If the quotient is a whole number, then 2 and 19,303,368.5 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 | 38,606,737 | |
| -1 | -38,606,737 |
Now, we try dividing 38,606,737 by 3:
38,606,737 ÷ 3 = 12,868,912.3333
If the quotient is a whole number, then 3 and 12,868,912.3333 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 | 38,606,737 | |
| -1 | -38,606,737 |
Let's try dividing by 4:
38,606,737 ÷ 4 = 9,651,684.25
If the quotient is a whole number, then 4 and 9,651,684.25 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 | 38,606,737 | |
| -1 | 38,606,737 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 137 | 409 | 689 | 1,781 | 5,317 | 7,261 | 21,677 | 56,033 | 94,393 | 281,801 | 728,429 | 2,969,749 | 38,606,737 |
| -1 | -13 | -53 | -137 | -409 | -689 | -1,781 | -5,317 | -7,261 | -21,677 | -56,033 | -94,393 | -281,801 | -728,429 | -2,969,749 | -38,606,737 |
