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 40,002,037, 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 | 40,002,037 | |
| -1 | -40,002,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,002,037.
Example:
1 x 40,002,037 = 40,002,037
and
-1 x -40,002,037 = 40,002,037
Notice both answers equal 40,002,037
With that explanation out of the way, let's continue. Next, we take the number 40,002,037 and divide it by 2:
40,002,037 ÷ 2 = 20,001,018.5
If the quotient is a whole number, then 2 and 20,001,018.5 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 | 40,002,037 | |
| -1 | -40,002,037 |
Now, we try dividing 40,002,037 by 3:
40,002,037 ÷ 3 = 13,334,012.3333
If the quotient is a whole number, then 3 and 13,334,012.3333 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 | 40,002,037 | |
| -1 | -40,002,037 |
Let's try dividing by 4:
40,002,037 ÷ 4 = 10,000,509.25
If the quotient is a whole number, then 4 and 10,000,509.25 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 | 40,002,037 | |
| -1 | 40,002,037 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 263 | 389 | 391 | 4,471 | 6,049 | 6,613 | 8,947 | 102,307 | 102,833 | 152,099 | 1,739,219 | 2,353,061 | 40,002,037 |
| -1 | -17 | -23 | -263 | -389 | -391 | -4,471 | -6,049 | -6,613 | -8,947 | -102,307 | -102,833 | -152,099 | -1,739,219 | -2,353,061 | -40,002,037 |
