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 254,633,165, 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 | 254,633,165 | |
| -1 | -254,633,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,633,165.
Example:
1 x 254,633,165 = 254,633,165
and
-1 x -254,633,165 = 254,633,165
Notice both answers equal 254,633,165
With that explanation out of the way, let's continue. Next, we take the number 254,633,165 and divide it by 2:
254,633,165 ÷ 2 = 127,316,582.5
If the quotient is a whole number, then 2 and 127,316,582.5 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 | 254,633,165 | |
| -1 | -254,633,165 |
Now, we try dividing 254,633,165 by 3:
254,633,165 ÷ 3 = 84,877,721.6667
If the quotient is a whole number, then 3 and 84,877,721.6667 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 | 254,633,165 | |
| -1 | -254,633,165 |
Let's try dividing by 4:
254,633,165 ÷ 4 = 63,658,291.25
If the quotient is a whole number, then 4 and 63,658,291.25 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 | 254,633,165 | |
| -1 | 254,633,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 67 | 205 | 335 | 2,747 | 13,735 | 18,539 | 92,695 | 760,099 | 1,242,113 | 3,800,495 | 6,210,565 | 50,926,633 | 254,633,165 |
| -1 | -5 | -41 | -67 | -205 | -335 | -2,747 | -13,735 | -18,539 | -92,695 | -760,099 | -1,242,113 | -3,800,495 | -6,210,565 | -50,926,633 | -254,633,165 |
