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 100,613,461, 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 | 100,613,461 | |
| -1 | -100,613,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,613,461.
Example:
1 x 100,613,461 = 100,613,461
and
-1 x -100,613,461 = 100,613,461
Notice both answers equal 100,613,461
With that explanation out of the way, let's continue. Next, we take the number 100,613,461 and divide it by 2:
100,613,461 ÷ 2 = 50,306,730.5
If the quotient is a whole number, then 2 and 50,306,730.5 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 | 100,613,461 | |
| -1 | -100,613,461 |
Now, we try dividing 100,613,461 by 3:
100,613,461 ÷ 3 = 33,537,820.3333
If the quotient is a whole number, then 3 and 33,537,820.3333 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 | 100,613,461 | |
| -1 | -100,613,461 |
Let's try dividing by 4:
100,613,461 ÷ 4 = 25,153,365.25
If the quotient is a whole number, then 4 and 25,153,365.25 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 | 100,613,461 | |
| -1 | 100,613,461 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 71 | 793 | 923 | 1,787 | 4,331 | 23,231 | 56,303 | 109,007 | 126,877 | 1,417,091 | 1,649,401 | 7,739,497 | 100,613,461 |
| -1 | -13 | -61 | -71 | -793 | -923 | -1,787 | -4,331 | -23,231 | -56,303 | -109,007 | -126,877 | -1,417,091 | -1,649,401 | -7,739,497 | -100,613,461 |
