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 40,424,657, 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 | 40,424,657 | |
| -1 | -40,424,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,424,657.
Example:
1 x 40,424,657 = 40,424,657
and
-1 x -40,424,657 = 40,424,657
Notice both answers equal 40,424,657
With that explanation out of the way, let's continue. Next, we take the number 40,424,657 and divide it by 2:
40,424,657 ÷ 2 = 20,212,328.5
If the quotient is a whole number, then 2 and 20,212,328.5 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 | 40,424,657 | |
| -1 | -40,424,657 |
Now, we try dividing 40,424,657 by 3:
40,424,657 ÷ 3 = 13,474,885.6667
If the quotient is a whole number, then 3 and 13,474,885.6667 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 | 40,424,657 | |
| -1 | -40,424,657 |
Let's try dividing by 4:
40,424,657 ÷ 4 = 10,106,164.25
If the quotient is a whole number, then 4 and 10,106,164.25 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 | 40,424,657 | |
| -1 | 40,424,657 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 49 | 91 | 119 | 221 | 637 | 833 | 1,547 | 3,733 | 10,829 | 26,131 | 48,529 | 63,461 | 182,917 | 339,703 | 444,227 | 824,993 | 2,377,921 | 3,109,589 | 5,774,951 | 40,424,657 |
| -1 | -7 | -13 | -17 | -49 | -91 | -119 | -221 | -637 | -833 | -1,547 | -3,733 | -10,829 | -26,131 | -48,529 | -63,461 | -182,917 | -339,703 | -444,227 | -824,993 | -2,377,921 | -3,109,589 | -5,774,951 | -40,424,657 |
