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 40,544,455, 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 | 40,544,455 | |
| -1 | -40,544,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,544,455.
Example:
1 x 40,544,455 = 40,544,455
and
-1 x -40,544,455 = 40,544,455
Notice both answers equal 40,544,455
With that explanation out of the way, let's continue. Next, we take the number 40,544,455 and divide it by 2:
40,544,455 ÷ 2 = 20,272,227.5
If the quotient is a whole number, then 2 and 20,272,227.5 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 | 40,544,455 | |
| -1 | -40,544,455 |
Now, we try dividing 40,544,455 by 3:
40,544,455 ÷ 3 = 13,514,818.3333
If the quotient is a whole number, then 3 and 13,514,818.3333 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 | 40,544,455 | |
| -1 | -40,544,455 |
Let's try dividing by 4:
40,544,455 ÷ 4 = 10,136,113.75
If the quotient is a whole number, then 4 and 10,136,113.75 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 | 40,544,455 | |
| -1 | 40,544,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 313 | 1,565 | 2,191 | 3,701 | 10,955 | 18,505 | 25,907 | 129,535 | 1,158,413 | 5,792,065 | 8,108,891 | 40,544,455 |
| -1 | -5 | -7 | -35 | -313 | -1,565 | -2,191 | -3,701 | -10,955 | -18,505 | -25,907 | -129,535 | -1,158,413 | -5,792,065 | -8,108,891 | -40,544,455 |
