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 167,713,325, 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 | 167,713,325 | |
| -1 | -167,713,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,713,325.
Example:
1 x 167,713,325 = 167,713,325
and
-1 x -167,713,325 = 167,713,325
Notice both answers equal 167,713,325
With that explanation out of the way, let's continue. Next, we take the number 167,713,325 and divide it by 2:
167,713,325 ÷ 2 = 83,856,662.5
If the quotient is a whole number, then 2 and 83,856,662.5 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 | 167,713,325 | |
| -1 | -167,713,325 |
Now, we try dividing 167,713,325 by 3:
167,713,325 ÷ 3 = 55,904,441.6667
If the quotient is a whole number, then 3 and 55,904,441.6667 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 | 167,713,325 | |
| -1 | -167,713,325 |
Let's try dividing by 4:
167,713,325 ÷ 4 = 41,928,331.25
If the quotient is a whole number, then 4 and 41,928,331.25 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 | 167,713,325 | |
| -1 | 167,713,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 325 | 491 | 1,051 | 2,455 | 5,255 | 6,383 | 12,275 | 13,663 | 26,275 | 31,915 | 68,315 | 159,575 | 341,575 | 516,041 | 2,580,205 | 6,708,533 | 12,901,025 | 33,542,665 | 167,713,325 |
| -1 | -5 | -13 | -25 | -65 | -325 | -491 | -1,051 | -2,455 | -5,255 | -6,383 | -12,275 | -13,663 | -26,275 | -31,915 | -68,315 | -159,575 | -341,575 | -516,041 | -2,580,205 | -6,708,533 | -12,901,025 | -33,542,665 | -167,713,325 |
