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 167,415,235, 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 | 167,415,235 | |
| -1 | -167,415,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,415,235.
Example:
1 x 167,415,235 = 167,415,235
and
-1 x -167,415,235 = 167,415,235
Notice both answers equal 167,415,235
With that explanation out of the way, let's continue. Next, we take the number 167,415,235 and divide it by 2:
167,415,235 ÷ 2 = 83,707,617.5
If the quotient is a whole number, then 2 and 83,707,617.5 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 | 167,415,235 | |
| -1 | -167,415,235 |
Now, we try dividing 167,415,235 by 3:
167,415,235 ÷ 3 = 55,805,078.3333
If the quotient is a whole number, then 3 and 55,805,078.3333 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 | 167,415,235 | |
| -1 | -167,415,235 |
Let's try dividing by 4:
167,415,235 ÷ 4 = 41,853,808.75
If the quotient is a whole number, then 4 and 41,853,808.75 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 | 167,415,235 | |
| -1 | 167,415,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 151,507 | 757,535 | 1,969,591 | 2,575,619 | 9,847,955 | 12,878,095 | 33,483,047 | 167,415,235 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -151,507 | -757,535 | -1,969,591 | -2,575,619 | -9,847,955 | -12,878,095 | -33,483,047 | -167,415,235 |
