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 38,854,435, 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 | 38,854,435 | |
| -1 | -38,854,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,854,435.
Example:
1 x 38,854,435 = 38,854,435
and
-1 x -38,854,435 = 38,854,435
Notice both answers equal 38,854,435
With that explanation out of the way, let's continue. Next, we take the number 38,854,435 and divide it by 2:
38,854,435 ÷ 2 = 19,427,217.5
If the quotient is a whole number, then 2 and 19,427,217.5 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 | 38,854,435 | |
| -1 | -38,854,435 |
Now, we try dividing 38,854,435 by 3:
38,854,435 ÷ 3 = 12,951,478.3333
If the quotient is a whole number, then 3 and 12,951,478.3333 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 | 38,854,435 | |
| -1 | -38,854,435 |
Let's try dividing by 4:
38,854,435 ÷ 4 = 9,713,608.75
If the quotient is a whole number, then 4 and 9,713,608.75 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 | 38,854,435 | |
| -1 | 38,854,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 331 | 1,381 | 1,655 | 5,627 | 6,905 | 23,477 | 28,135 | 117,385 | 457,111 | 2,285,555 | 7,770,887 | 38,854,435 |
| -1 | -5 | -17 | -85 | -331 | -1,381 | -1,655 | -5,627 | -6,905 | -23,477 | -28,135 | -117,385 | -457,111 | -2,285,555 | -7,770,887 | -38,854,435 |
