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 88,120,537, 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 | 88,120,537 | |
| -1 | -88,120,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,120,537.
Example:
1 x 88,120,537 = 88,120,537
and
-1 x -88,120,537 = 88,120,537
Notice both answers equal 88,120,537
With that explanation out of the way, let's continue. Next, we take the number 88,120,537 and divide it by 2:
88,120,537 ÷ 2 = 44,060,268.5
If the quotient is a whole number, then 2 and 44,060,268.5 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 | 88,120,537 | |
| -1 | -88,120,537 |
Now, we try dividing 88,120,537 by 3:
88,120,537 ÷ 3 = 29,373,512.3333
If the quotient is a whole number, then 3 and 29,373,512.3333 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 | 88,120,537 | |
| -1 | -88,120,537 |
Let's try dividing by 4:
88,120,537 ÷ 4 = 22,030,134.25
If the quotient is a whole number, then 4 and 22,030,134.25 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 | 88,120,537 | |
| -1 | 88,120,537 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 149 | 323 | 1,831 | 2,533 | 2,831 | 31,127 | 34,789 | 48,127 | 272,819 | 591,413 | 4,637,923 | 5,183,561 | 88,120,537 |
| -1 | -17 | -19 | -149 | -323 | -1,831 | -2,533 | -2,831 | -31,127 | -34,789 | -48,127 | -272,819 | -591,413 | -4,637,923 | -5,183,561 | -88,120,537 |
