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 41,154,113, 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 | 41,154,113 | |
| -1 | -41,154,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,154,113.
Example:
1 x 41,154,113 = 41,154,113
and
-1 x -41,154,113 = 41,154,113
Notice both answers equal 41,154,113
With that explanation out of the way, let's continue. Next, we take the number 41,154,113 and divide it by 2:
41,154,113 ÷ 2 = 20,577,056.5
If the quotient is a whole number, then 2 and 20,577,056.5 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 | 41,154,113 | |
| -1 | -41,154,113 |
Now, we try dividing 41,154,113 by 3:
41,154,113 ÷ 3 = 13,718,037.6667
If the quotient is a whole number, then 3 and 13,718,037.6667 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 | 41,154,113 | |
| -1 | -41,154,113 |
Let's try dividing by 4:
41,154,113 ÷ 4 = 10,288,528.25
If the quotient is a whole number, then 4 and 10,288,528.25 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 | 41,154,113 | |
| -1 | 41,154,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 41,113 | 287,791 | 452,243 | 534,469 | 3,165,701 | 3,741,283 | 5,879,159 | 41,154,113 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -41,113 | -287,791 | -452,243 | -534,469 | -3,165,701 | -3,741,283 | -5,879,159 | -41,154,113 |
