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 40,374,061, 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 | 40,374,061 | |
| -1 | -40,374,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,374,061.
Example:
1 x 40,374,061 = 40,374,061
and
-1 x -40,374,061 = 40,374,061
Notice both answers equal 40,374,061
With that explanation out of the way, let's continue. Next, we take the number 40,374,061 and divide it by 2:
40,374,061 ÷ 2 = 20,187,030.5
If the quotient is a whole number, then 2 and 20,187,030.5 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 | 40,374,061 | |
| -1 | -40,374,061 |
Now, we try dividing 40,374,061 by 3:
40,374,061 ÷ 3 = 13,458,020.3333
If the quotient is a whole number, then 3 and 13,458,020.3333 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 | 40,374,061 | |
| -1 | -40,374,061 |
Let's try dividing by 4:
40,374,061 ÷ 4 = 10,093,515.25
If the quotient is a whole number, then 4 and 10,093,515.25 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 | 40,374,061 | |
| -1 | 40,374,061 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 2,639 | 15,299 | 107,093 | 198,887 | 443,671 | 1,392,209 | 3,105,697 | 5,767,723 | 40,374,061 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -2,639 | -15,299 | -107,093 | -198,887 | -443,671 | -1,392,209 | -3,105,697 | -5,767,723 | -40,374,061 |
