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 167,853,631, 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 | 167,853,631 | |
| -1 | -167,853,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,853,631.
Example:
1 x 167,853,631 = 167,853,631
and
-1 x -167,853,631 = 167,853,631
Notice both answers equal 167,853,631
With that explanation out of the way, let's continue. Next, we take the number 167,853,631 and divide it by 2:
167,853,631 ÷ 2 = 83,926,815.5
If the quotient is a whole number, then 2 and 83,926,815.5 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 | 167,853,631 | |
| -1 | -167,853,631 |
Now, we try dividing 167,853,631 by 3:
167,853,631 ÷ 3 = 55,951,210.3333
If the quotient is a whole number, then 3 and 55,951,210.3333 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 | 167,853,631 | |
| -1 | -167,853,631 |
Let's try dividing by 4:
167,853,631 ÷ 4 = 41,963,407.75
If the quotient is a whole number, then 4 and 41,963,407.75 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 | 167,853,631 | |
| -1 | 167,853,631 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 451 | 697 | 7,667 | 21,893 | 240,823 | 372,181 | 897,613 | 4,093,991 | 9,873,743 | 15,259,421 | 167,853,631 |
| -1 | -11 | -17 | -41 | -187 | -451 | -697 | -7,667 | -21,893 | -240,823 | -372,181 | -897,613 | -4,093,991 | -9,873,743 | -15,259,421 | -167,853,631 |
