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 115,902,475, 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 | 115,902,475 | |
| -1 | -115,902,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,902,475.
Example:
1 x 115,902,475 = 115,902,475
and
-1 x -115,902,475 = 115,902,475
Notice both answers equal 115,902,475
With that explanation out of the way, let's continue. Next, we take the number 115,902,475 and divide it by 2:
115,902,475 ÷ 2 = 57,951,237.5
If the quotient is a whole number, then 2 and 57,951,237.5 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 | 115,902,475 | |
| -1 | -115,902,475 |
Now, we try dividing 115,902,475 by 3:
115,902,475 ÷ 3 = 38,634,158.3333
If the quotient is a whole number, then 3 and 38,634,158.3333 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 | 115,902,475 | |
| -1 | -115,902,475 |
Let's try dividing by 4:
115,902,475 ÷ 4 = 28,975,618.75
If the quotient is a whole number, then 4 and 28,975,618.75 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 | 115,902,475 | |
| -1 | 115,902,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 89 | 325 | 445 | 1,157 | 2,225 | 4,007 | 5,785 | 20,035 | 28,925 | 52,091 | 100,175 | 260,455 | 356,623 | 1,302,275 | 1,783,115 | 4,636,099 | 8,915,575 | 23,180,495 | 115,902,475 |
| -1 | -5 | -13 | -25 | -65 | -89 | -325 | -445 | -1,157 | -2,225 | -4,007 | -5,785 | -20,035 | -28,925 | -52,091 | -100,175 | -260,455 | -356,623 | -1,302,275 | -1,783,115 | -4,636,099 | -8,915,575 | -23,180,495 | -115,902,475 |
