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 37,153,165, 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 | 37,153,165 | |
| -1 | -37,153,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,153,165.
Example:
1 x 37,153,165 = 37,153,165
and
-1 x -37,153,165 = 37,153,165
Notice both answers equal 37,153,165
With that explanation out of the way, let's continue. Next, we take the number 37,153,165 and divide it by 2:
37,153,165 ÷ 2 = 18,576,582.5
If the quotient is a whole number, then 2 and 18,576,582.5 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 | 37,153,165 | |
| -1 | -37,153,165 |
Now, we try dividing 37,153,165 by 3:
37,153,165 ÷ 3 = 12,384,388.3333
If the quotient is a whole number, then 3 and 12,384,388.3333 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 | 37,153,165 | |
| -1 | -37,153,165 |
Let's try dividing by 4:
37,153,165 ÷ 4 = 9,288,291.25
If the quotient is a whole number, then 4 and 9,288,291.25 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 | 37,153,165 | |
| -1 | 37,153,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 46,153 | 230,765 | 323,071 | 1,061,519 | 1,615,355 | 5,307,595 | 7,430,633 | 37,153,165 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -46,153 | -230,765 | -323,071 | -1,061,519 | -1,615,355 | -5,307,595 | -7,430,633 | -37,153,165 |
