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 38,646,875, 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 | 38,646,875 | |
| -1 | -38,646,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,646,875.
Example:
1 x 38,646,875 = 38,646,875
and
-1 x -38,646,875 = 38,646,875
Notice both answers equal 38,646,875
With that explanation out of the way, let's continue. Next, we take the number 38,646,875 and divide it by 2:
38,646,875 ÷ 2 = 19,323,437.5
If the quotient is a whole number, then 2 and 19,323,437.5 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 | 38,646,875 | |
| -1 | -38,646,875 |
Now, we try dividing 38,646,875 by 3:
38,646,875 ÷ 3 = 12,882,291.6667
If the quotient is a whole number, then 3 and 12,882,291.6667 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 | 38,646,875 | |
| -1 | -38,646,875 |
Let's try dividing by 4:
38,646,875 ÷ 4 = 9,661,718.75
If the quotient is a whole number, then 4 and 9,661,718.75 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 | 38,646,875 | |
| -1 | 38,646,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 125 | 149 | 415 | 625 | 745 | 2,075 | 3,125 | 3,725 | 10,375 | 12,367 | 18,625 | 51,875 | 61,835 | 93,125 | 259,375 | 309,175 | 465,625 | 1,545,875 | 7,729,375 | 38,646,875 |
| -1 | -5 | -25 | -83 | -125 | -149 | -415 | -625 | -745 | -2,075 | -3,125 | -3,725 | -10,375 | -12,367 | -18,625 | -51,875 | -61,835 | -93,125 | -259,375 | -309,175 | -465,625 | -1,545,875 | -7,729,375 | -38,646,875 |
