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 40,448,551, 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 | 40,448,551 | |
| -1 | -40,448,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,448,551.
Example:
1 x 40,448,551 = 40,448,551
and
-1 x -40,448,551 = 40,448,551
Notice both answers equal 40,448,551
With that explanation out of the way, let's continue. Next, we take the number 40,448,551 and divide it by 2:
40,448,551 ÷ 2 = 20,224,275.5
If the quotient is a whole number, then 2 and 20,224,275.5 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 | 40,448,551 | |
| -1 | -40,448,551 |
Now, we try dividing 40,448,551 by 3:
40,448,551 ÷ 3 = 13,482,850.3333
If the quotient is a whole number, then 3 and 13,482,850.3333 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 | 40,448,551 | |
| -1 | -40,448,551 |
Let's try dividing by 4:
40,448,551 ÷ 4 = 10,112,137.75
If the quotient is a whole number, then 4 and 10,112,137.75 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 | 40,448,551 | |
| -1 | 40,448,551 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 671 | 793 | 4,637 | 8,723 | 51,007 | 60,281 | 282,857 | 663,091 | 3,111,427 | 3,677,141 | 40,448,551 |
| -1 | -11 | -13 | -61 | -143 | -671 | -793 | -4,637 | -8,723 | -51,007 | -60,281 | -282,857 | -663,091 | -3,111,427 | -3,677,141 | -40,448,551 |
