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 88,105,283, 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 | 88,105,283 | |
| -1 | -88,105,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,105,283.
Example:
1 x 88,105,283 = 88,105,283
and
-1 x -88,105,283 = 88,105,283
Notice both answers equal 88,105,283
With that explanation out of the way, let's continue. Next, we take the number 88,105,283 and divide it by 2:
88,105,283 ÷ 2 = 44,052,641.5
If the quotient is a whole number, then 2 and 44,052,641.5 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 | 88,105,283 | |
| -1 | -88,105,283 |
Now, we try dividing 88,105,283 by 3:
88,105,283 ÷ 3 = 29,368,427.6667
If the quotient is a whole number, then 3 and 29,368,427.6667 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 | 88,105,283 | |
| -1 | -88,105,283 |
Let's try dividing by 4:
88,105,283 ÷ 4 = 22,026,320.75
If the quotient is a whole number, then 4 and 22,026,320.75 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 | 88,105,283 | |
| -1 | 88,105,283 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 89 | 227 | 623 | 1,589 | 4,361 | 7,921 | 11,123 | 20,203 | 55,447 | 141,421 | 388,129 | 989,947 | 1,798,067 | 12,586,469 | 88,105,283 |
| -1 | -7 | -49 | -89 | -227 | -623 | -1,589 | -4,361 | -7,921 | -11,123 | -20,203 | -55,447 | -141,421 | -388,129 | -989,947 | -1,798,067 | -12,586,469 | -88,105,283 |
