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 38,038,045, 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 | 38,038,045 | |
| -1 | -38,038,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,038,045.
Example:
1 x 38,038,045 = 38,038,045
and
-1 x -38,038,045 = 38,038,045
Notice both answers equal 38,038,045
With that explanation out of the way, let's continue. Next, we take the number 38,038,045 and divide it by 2:
38,038,045 ÷ 2 = 19,019,022.5
If the quotient is a whole number, then 2 and 19,019,022.5 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 | 38,038,045 | |
| -1 | -38,038,045 |
Now, we try dividing 38,038,045 by 3:
38,038,045 ÷ 3 = 12,679,348.3333
If the quotient is a whole number, then 3 and 12,679,348.3333 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 | 38,038,045 | |
| -1 | -38,038,045 |
Let's try dividing by 4:
38,038,045 ÷ 4 = 9,509,511.25
If the quotient is a whole number, then 4 and 9,509,511.25 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 | 38,038,045 | |
| -1 | 38,038,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 139 | 229 | 239 | 695 | 1,145 | 1,195 | 31,831 | 33,221 | 54,731 | 159,155 | 166,105 | 273,655 | 7,607,609 | 38,038,045 |
| -1 | -5 | -139 | -229 | -239 | -695 | -1,145 | -1,195 | -31,831 | -33,221 | -54,731 | -159,155 | -166,105 | -273,655 | -7,607,609 | -38,038,045 |
