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 167,472,385, 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 | 167,472,385 | |
| -1 | -167,472,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,472,385.
Example:
1 x 167,472,385 = 167,472,385
and
-1 x -167,472,385 = 167,472,385
Notice both answers equal 167,472,385
With that explanation out of the way, let's continue. Next, we take the number 167,472,385 and divide it by 2:
167,472,385 ÷ 2 = 83,736,192.5
If the quotient is a whole number, then 2 and 83,736,192.5 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 | 167,472,385 | |
| -1 | -167,472,385 |
Now, we try dividing 167,472,385 by 3:
167,472,385 ÷ 3 = 55,824,128.3333
If the quotient is a whole number, then 3 and 55,824,128.3333 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 | 167,472,385 | |
| -1 | -167,472,385 |
Let's try dividing by 4:
167,472,385 ÷ 4 = 41,868,096.25
If the quotient is a whole number, then 4 and 41,868,096.25 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 | 167,472,385 | |
| -1 | 167,472,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 59 | 155 | 295 | 1,829 | 9,145 | 18,313 | 91,565 | 567,703 | 1,080,467 | 2,838,515 | 5,402,335 | 33,494,477 | 167,472,385 |
| -1 | -5 | -31 | -59 | -155 | -295 | -1,829 | -9,145 | -18,313 | -91,565 | -567,703 | -1,080,467 | -2,838,515 | -5,402,335 | -33,494,477 | -167,472,385 |
