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 167,369,251, 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 | 167,369,251 | |
| -1 | -167,369,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,369,251.
Example:
1 x 167,369,251 = 167,369,251
and
-1 x -167,369,251 = 167,369,251
Notice both answers equal 167,369,251
With that explanation out of the way, let's continue. Next, we take the number 167,369,251 and divide it by 2:
167,369,251 ÷ 2 = 83,684,625.5
If the quotient is a whole number, then 2 and 83,684,625.5 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 | 167,369,251 | |
| -1 | -167,369,251 |
Now, we try dividing 167,369,251 by 3:
167,369,251 ÷ 3 = 55,789,750.3333
If the quotient is a whole number, then 3 and 55,789,750.3333 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 | 167,369,251 | |
| -1 | -167,369,251 |
Let's try dividing by 4:
167,369,251 ÷ 4 = 41,842,312.75
If the quotient is a whole number, then 4 and 41,842,312.75 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 | 167,369,251 | |
| -1 | 167,369,251 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 83 | 343 | 581 | 4,067 | 5,879 | 28,469 | 41,153 | 288,071 | 487,957 | 2,016,497 | 3,415,699 | 23,909,893 | 167,369,251 |
| -1 | -7 | -49 | -83 | -343 | -581 | -4,067 | -5,879 | -28,469 | -41,153 | -288,071 | -487,957 | -2,016,497 | -3,415,699 | -23,909,893 | -167,369,251 |
