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 40,571,335, 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 | 40,571,335 | |
| -1 | -40,571,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,571,335.
Example:
1 x 40,571,335 = 40,571,335
and
-1 x -40,571,335 = 40,571,335
Notice both answers equal 40,571,335
With that explanation out of the way, let's continue. Next, we take the number 40,571,335 and divide it by 2:
40,571,335 ÷ 2 = 20,285,667.5
If the quotient is a whole number, then 2 and 20,285,667.5 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 | 40,571,335 | |
| -1 | -40,571,335 |
Now, we try dividing 40,571,335 by 3:
40,571,335 ÷ 3 = 13,523,778.3333
If the quotient is a whole number, then 3 and 13,523,778.3333 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 | 40,571,335 | |
| -1 | -40,571,335 |
Let's try dividing by 4:
40,571,335 ÷ 4 = 10,142,833.75
If the quotient is a whole number, then 4 and 10,142,833.75 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 | 40,571,335 | |
| -1 | 40,571,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 659 | 1,759 | 3,295 | 4,613 | 8,795 | 12,313 | 23,065 | 61,565 | 1,159,181 | 5,795,905 | 8,114,267 | 40,571,335 |
| -1 | -5 | -7 | -35 | -659 | -1,759 | -3,295 | -4,613 | -8,795 | -12,313 | -23,065 | -61,565 | -1,159,181 | -5,795,905 | -8,114,267 | -40,571,335 |
