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 153,442,303, 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 | 153,442,303 | |
| -1 | -153,442,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,442,303.
Example:
1 x 153,442,303 = 153,442,303
and
-1 x -153,442,303 = 153,442,303
Notice both answers equal 153,442,303
With that explanation out of the way, let's continue. Next, we take the number 153,442,303 and divide it by 2:
153,442,303 ÷ 2 = 76,721,151.5
If the quotient is a whole number, then 2 and 76,721,151.5 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 | 153,442,303 | |
| -1 | -153,442,303 |
Now, we try dividing 153,442,303 by 3:
153,442,303 ÷ 3 = 51,147,434.3333
If the quotient is a whole number, then 3 and 51,147,434.3333 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 | 153,442,303 | |
| -1 | -153,442,303 |
Let's try dividing by 4:
153,442,303 ÷ 4 = 38,360,575.75
If the quotient is a whole number, then 4 and 38,360,575.75 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 | 153,442,303 | |
| -1 | 153,442,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 313 | 413 | 1,187 | 2,191 | 8,309 | 18,467 | 70,033 | 129,269 | 371,531 | 490,231 | 2,600,717 | 21,920,329 | 153,442,303 |
| -1 | -7 | -59 | -313 | -413 | -1,187 | -2,191 | -8,309 | -18,467 | -70,033 | -129,269 | -371,531 | -490,231 | -2,600,717 | -21,920,329 | -153,442,303 |
