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 38,505,701, 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 | 38,505,701 | |
| -1 | -38,505,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,505,701.
Example:
1 x 38,505,701 = 38,505,701
and
-1 x -38,505,701 = 38,505,701
Notice both answers equal 38,505,701
With that explanation out of the way, let's continue. Next, we take the number 38,505,701 and divide it by 2:
38,505,701 ÷ 2 = 19,252,850.5
If the quotient is a whole number, then 2 and 19,252,850.5 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 | 38,505,701 | |
| -1 | -38,505,701 |
Now, we try dividing 38,505,701 by 3:
38,505,701 ÷ 3 = 12,835,233.6667
If the quotient is a whole number, then 3 and 12,835,233.6667 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 | 38,505,701 | |
| -1 | -38,505,701 |
Let's try dividing by 4:
38,505,701 ÷ 4 = 9,626,425.25
If the quotient is a whole number, then 4 and 9,626,425.25 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 | 38,505,701 | |
| -1 | 38,505,701 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 61 | 767 | 793 | 823 | 3,599 | 10,699 | 46,787 | 48,557 | 50,203 | 631,241 | 652,639 | 2,961,977 | 38,505,701 |
| -1 | -13 | -59 | -61 | -767 | -793 | -823 | -3,599 | -10,699 | -46,787 | -48,557 | -50,203 | -631,241 | -652,639 | -2,961,977 | -38,505,701 |
