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 167,635,853, 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 | 167,635,853 | |
| -1 | -167,635,853 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,635,853.
Example:
1 x 167,635,853 = 167,635,853
and
-1 x -167,635,853 = 167,635,853
Notice both answers equal 167,635,853
With that explanation out of the way, let's continue. Next, we take the number 167,635,853 and divide it by 2:
167,635,853 ÷ 2 = 83,817,926.5
If the quotient is a whole number, then 2 and 83,817,926.5 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 | 167,635,853 | |
| -1 | -167,635,853 |
Now, we try dividing 167,635,853 by 3:
167,635,853 ÷ 3 = 55,878,617.6667
If the quotient is a whole number, then 3 and 55,878,617.6667 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 | 167,635,853 | |
| -1 | -167,635,853 |
Let's try dividing by 4:
167,635,853 ÷ 4 = 41,908,963.25
If the quotient is a whole number, then 4 and 41,908,963.25 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 | 167,635,853 | |
| -1 | 167,635,853 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 131 | 917 | 1,441 | 10,087 | 16,619 | 116,333 | 182,809 | 1,279,663 | 2,177,089 | 15,239,623 | 23,947,979 | 167,635,853 |
| -1 | -7 | -11 | -77 | -131 | -917 | -1,441 | -10,087 | -16,619 | -116,333 | -182,809 | -1,279,663 | -2,177,089 | -15,239,623 | -23,947,979 | -167,635,853 |
