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 147,290,057, 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 | 147,290,057 | |
| -1 | -147,290,057 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,290,057.
Example:
1 x 147,290,057 = 147,290,057
and
-1 x -147,290,057 = 147,290,057
Notice both answers equal 147,290,057
With that explanation out of the way, let's continue. Next, we take the number 147,290,057 and divide it by 2:
147,290,057 ÷ 2 = 73,645,028.5
If the quotient is a whole number, then 2 and 73,645,028.5 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 | 147,290,057 | |
| -1 | -147,290,057 |
Now, we try dividing 147,290,057 by 3:
147,290,057 ÷ 3 = 49,096,685.6667
If the quotient is a whole number, then 3 and 49,096,685.6667 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 | 147,290,057 | |
| -1 | -147,290,057 |
Let's try dividing by 4:
147,290,057 ÷ 4 = 36,822,514.25
If the quotient is a whole number, then 4 and 36,822,514.25 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 | 147,290,057 | |
| -1 | 147,290,057 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 83 | 799 | 1,411 | 2,221 | 3,901 | 37,757 | 66,317 | 104,387 | 184,343 | 1,774,579 | 3,133,831 | 8,664,121 | 147,290,057 |
| -1 | -17 | -47 | -83 | -799 | -1,411 | -2,221 | -3,901 | -37,757 | -66,317 | -104,387 | -184,343 | -1,774,579 | -3,133,831 | -8,664,121 | -147,290,057 |
