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 167,321,275, 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 | 167,321,275 | |
| -1 | -167,321,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,321,275.
Example:
1 x 167,321,275 = 167,321,275
and
-1 x -167,321,275 = 167,321,275
Notice both answers equal 167,321,275
With that explanation out of the way, let's continue. Next, we take the number 167,321,275 and divide it by 2:
167,321,275 ÷ 2 = 83,660,637.5
If the quotient is a whole number, then 2 and 83,660,637.5 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 | 167,321,275 | |
| -1 | -167,321,275 |
Now, we try dividing 167,321,275 by 3:
167,321,275 ÷ 3 = 55,773,758.3333
If the quotient is a whole number, then 3 and 55,773,758.3333 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 | 167,321,275 | |
| -1 | -167,321,275 |
Let's try dividing by 4:
167,321,275 ÷ 4 = 41,830,318.75
If the quotient is a whole number, then 4 and 41,830,318.75 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 | 167,321,275 | |
| -1 | 167,321,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 173 | 275 | 865 | 1,903 | 3,517 | 4,325 | 9,515 | 17,585 | 38,687 | 47,575 | 87,925 | 193,435 | 608,441 | 967,175 | 3,042,205 | 6,692,851 | 15,211,025 | 33,464,255 | 167,321,275 |
| -1 | -5 | -11 | -25 | -55 | -173 | -275 | -865 | -1,903 | -3,517 | -4,325 | -9,515 | -17,585 | -38,687 | -47,575 | -87,925 | -193,435 | -608,441 | -967,175 | -3,042,205 | -6,692,851 | -15,211,025 | -33,464,255 | -167,321,275 |
