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 100,252,537, 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 | 100,252,537 | |
| -1 | -100,252,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,252,537.
Example:
1 x 100,252,537 = 100,252,537
and
-1 x -100,252,537 = 100,252,537
Notice both answers equal 100,252,537
With that explanation out of the way, let's continue. Next, we take the number 100,252,537 and divide it by 2:
100,252,537 ÷ 2 = 50,126,268.5
If the quotient is a whole number, then 2 and 50,126,268.5 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 | 100,252,537 | |
| -1 | -100,252,537 |
Now, we try dividing 100,252,537 by 3:
100,252,537 ÷ 3 = 33,417,512.3333
If the quotient is a whole number, then 3 and 33,417,512.3333 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 | 100,252,537 | |
| -1 | -100,252,537 |
Let's try dividing by 4:
100,252,537 ÷ 4 = 25,063,134.25
If the quotient is a whole number, then 4 and 25,063,134.25 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 | 100,252,537 | |
| -1 | 100,252,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 89 | 623 | 979 | 6,853 | 14,629 | 102,403 | 160,919 | 1,126,433 | 1,301,981 | 9,113,867 | 14,321,791 | 100,252,537 |
| -1 | -7 | -11 | -77 | -89 | -623 | -979 | -6,853 | -14,629 | -102,403 | -160,919 | -1,126,433 | -1,301,981 | -9,113,867 | -14,321,791 | -100,252,537 |
