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 40,741,961, 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 | 40,741,961 | |
| -1 | -40,741,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,741,961.
Example:
1 x 40,741,961 = 40,741,961
and
-1 x -40,741,961 = 40,741,961
Notice both answers equal 40,741,961
With that explanation out of the way, let's continue. Next, we take the number 40,741,961 and divide it by 2:
40,741,961 ÷ 2 = 20,370,980.5
If the quotient is a whole number, then 2 and 20,370,980.5 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 | 40,741,961 | |
| -1 | -40,741,961 |
Now, we try dividing 40,741,961 by 3:
40,741,961 ÷ 3 = 13,580,653.6667
If the quotient is a whole number, then 3 and 13,580,653.6667 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 | 40,741,961 | |
| -1 | -40,741,961 |
Let's try dividing by 4:
40,741,961 ÷ 4 = 10,185,490.25
If the quotient is a whole number, then 4 and 10,185,490.25 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 | 40,741,961 | |
| -1 | 40,741,961 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 83 | 619 | 793 | 1,079 | 5,063 | 8,047 | 37,759 | 51,377 | 65,819 | 490,867 | 667,901 | 3,133,997 | 40,741,961 |
| -1 | -13 | -61 | -83 | -619 | -793 | -1,079 | -5,063 | -8,047 | -37,759 | -51,377 | -65,819 | -490,867 | -667,901 | -3,133,997 | -40,741,961 |
