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 147,264,001, 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 | 147,264,001 | |
| -1 | -147,264,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,264,001.
Example:
1 x 147,264,001 = 147,264,001
and
-1 x -147,264,001 = 147,264,001
Notice both answers equal 147,264,001
With that explanation out of the way, let's continue. Next, we take the number 147,264,001 and divide it by 2:
147,264,001 ÷ 2 = 73,632,000.5
If the quotient is a whole number, then 2 and 73,632,000.5 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 | 147,264,001 | |
| -1 | -147,264,001 |
Now, we try dividing 147,264,001 by 3:
147,264,001 ÷ 3 = 49,088,000.3333
If the quotient is a whole number, then 3 and 49,088,000.3333 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 | 147,264,001 | |
| -1 | -147,264,001 |
Let's try dividing by 4:
147,264,001 ÷ 4 = 36,816,000.25
If the quotient is a whole number, then 4 and 36,816,000.25 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 | 147,264,001 | |
| -1 | 147,264,001 |
If you did it right, you will end up with this table:
| 1 | 29 | 149 | 173 | 197 | 4,321 | 5,017 | 5,713 | 25,777 | 29,353 | 34,081 | 747,533 | 851,237 | 988,349 | 5,078,069 | 147,264,001 |
| -1 | -29 | -149 | -173 | -197 | -4,321 | -5,017 | -5,713 | -25,777 | -29,353 | -34,081 | -747,533 | -851,237 | -988,349 | -5,078,069 | -147,264,001 |
