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 147,603,521, 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 | 147,603,521 | |
| -1 | -147,603,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,603,521.
Example:
1 x 147,603,521 = 147,603,521
and
-1 x -147,603,521 = 147,603,521
Notice both answers equal 147,603,521
With that explanation out of the way, let's continue. Next, we take the number 147,603,521 and divide it by 2:
147,603,521 ÷ 2 = 73,801,760.5
If the quotient is a whole number, then 2 and 73,801,760.5 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 | 147,603,521 | |
| -1 | -147,603,521 |
Now, we try dividing 147,603,521 by 3:
147,603,521 ÷ 3 = 49,201,173.6667
If the quotient is a whole number, then 3 and 49,201,173.6667 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 | 147,603,521 | |
| -1 | -147,603,521 |
Let's try dividing by 4:
147,603,521 ÷ 4 = 36,900,880.25
If the quotient is a whole number, then 4 and 36,900,880.25 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 | 147,603,521 | |
| -1 | 147,603,521 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 101 | 1,027 | 1,313 | 1,423 | 7,979 | 18,499 | 103,727 | 112,417 | 143,723 | 1,461,421 | 1,868,399 | 11,354,117 | 147,603,521 |
| -1 | -13 | -79 | -101 | -1,027 | -1,313 | -1,423 | -7,979 | -18,499 | -103,727 | -112,417 | -143,723 | -1,461,421 | -1,868,399 | -11,354,117 | -147,603,521 |
