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 116,374,531, 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 | 116,374,531 | |
| -1 | -116,374,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,374,531.
Example:
1 x 116,374,531 = 116,374,531
and
-1 x -116,374,531 = 116,374,531
Notice both answers equal 116,374,531
With that explanation out of the way, let's continue. Next, we take the number 116,374,531 and divide it by 2:
116,374,531 ÷ 2 = 58,187,265.5
If the quotient is a whole number, then 2 and 58,187,265.5 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 | 116,374,531 | |
| -1 | -116,374,531 |
Now, we try dividing 116,374,531 by 3:
116,374,531 ÷ 3 = 38,791,510.3333
If the quotient is a whole number, then 3 and 38,791,510.3333 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 | 116,374,531 | |
| -1 | -116,374,531 |
Let's try dividing by 4:
116,374,531 ÷ 4 = 29,093,632.75
If the quotient is a whole number, then 4 and 29,093,632.75 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 | 116,374,531 | |
| -1 | 116,374,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 89 | 91 | 623 | 1,157 | 8,099 | 14,369 | 100,583 | 186,797 | 1,278,841 | 1,307,579 | 8,951,887 | 16,624,933 | 116,374,531 |
| -1 | -7 | -13 | -89 | -91 | -623 | -1,157 | -8,099 | -14,369 | -100,583 | -186,797 | -1,278,841 | -1,307,579 | -8,951,887 | -16,624,933 | -116,374,531 |
