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 153,231,455, 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 | 153,231,455 | |
| -1 | -153,231,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,231,455.
Example:
1 x 153,231,455 = 153,231,455
and
-1 x -153,231,455 = 153,231,455
Notice both answers equal 153,231,455
With that explanation out of the way, let's continue. Next, we take the number 153,231,455 and divide it by 2:
153,231,455 ÷ 2 = 76,615,727.5
If the quotient is a whole number, then 2 and 76,615,727.5 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 | 153,231,455 | |
| -1 | -153,231,455 |
Now, we try dividing 153,231,455 by 3:
153,231,455 ÷ 3 = 51,077,151.6667
If the quotient is a whole number, then 3 and 51,077,151.6667 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 | 153,231,455 | |
| -1 | -153,231,455 |
Let's try dividing by 4:
153,231,455 ÷ 4 = 38,307,863.75
If the quotient is a whole number, then 4 and 38,307,863.75 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 | 153,231,455 | |
| -1 | 153,231,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 169 | 221 | 845 | 1,105 | 2,873 | 10,667 | 14,365 | 53,335 | 138,671 | 181,339 | 693,355 | 906,695 | 1,802,723 | 2,357,407 | 9,013,615 | 11,787,035 | 30,646,291 | 153,231,455 |
| -1 | -5 | -13 | -17 | -65 | -85 | -169 | -221 | -845 | -1,105 | -2,873 | -10,667 | -14,365 | -53,335 | -138,671 | -181,339 | -693,355 | -906,695 | -1,802,723 | -2,357,407 | -9,013,615 | -11,787,035 | -30,646,291 | -153,231,455 |
