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 153,144,511, 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 | 153,144,511 | |
| -1 | -153,144,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,144,511.
Example:
1 x 153,144,511 = 153,144,511
and
-1 x -153,144,511 = 153,144,511
Notice both answers equal 153,144,511
With that explanation out of the way, let's continue. Next, we take the number 153,144,511 and divide it by 2:
153,144,511 ÷ 2 = 76,572,255.5
If the quotient is a whole number, then 2 and 76,572,255.5 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 | 153,144,511 | |
| -1 | -153,144,511 |
Now, we try dividing 153,144,511 by 3:
153,144,511 ÷ 3 = 51,048,170.3333
If the quotient is a whole number, then 3 and 51,048,170.3333 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 | 153,144,511 | |
| -1 | -153,144,511 |
Let's try dividing by 4:
153,144,511 ÷ 4 = 38,286,127.75
If the quotient is a whole number, then 4 and 38,286,127.75 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 | 153,144,511 | |
| -1 | 153,144,511 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 167 | 299 | 2,171 | 3,067 | 3,841 | 39,871 | 49,933 | 70,541 | 512,189 | 917,033 | 6,658,457 | 11,780,347 | 153,144,511 |
| -1 | -13 | -23 | -167 | -299 | -2,171 | -3,067 | -3,841 | -39,871 | -49,933 | -70,541 | -512,189 | -917,033 | -6,658,457 | -11,780,347 | -153,144,511 |
