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 88,871,149, 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 | 88,871,149 | |
| -1 | -88,871,149 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,871,149.
Example:
1 x 88,871,149 = 88,871,149
and
-1 x -88,871,149 = 88,871,149
Notice both answers equal 88,871,149
With that explanation out of the way, let's continue. Next, we take the number 88,871,149 and divide it by 2:
88,871,149 ÷ 2 = 44,435,574.5
If the quotient is a whole number, then 2 and 44,435,574.5 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 | 88,871,149 | |
| -1 | -88,871,149 |
Now, we try dividing 88,871,149 by 3:
88,871,149 ÷ 3 = 29,623,716.3333
If the quotient is a whole number, then 3 and 29,623,716.3333 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 | 88,871,149 | |
| -1 | -88,871,149 |
Let's try dividing by 4:
88,871,149 ÷ 4 = 22,217,787.25
If the quotient is a whole number, then 4 and 22,217,787.25 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 | 88,871,149 | |
| -1 | 88,871,149 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 73 | 943 | 1,291 | 1,679 | 2,993 | 29,693 | 52,931 | 68,839 | 94,243 | 1,217,413 | 2,167,589 | 3,863,963 | 88,871,149 |
| -1 | -23 | -41 | -73 | -943 | -1,291 | -1,679 | -2,993 | -29,693 | -52,931 | -68,839 | -94,243 | -1,217,413 | -2,167,589 | -3,863,963 | -88,871,149 |
