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 45,531,655, 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 | 45,531,655 | |
| -1 | -45,531,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,531,655.
Example:
1 x 45,531,655 = 45,531,655
and
-1 x -45,531,655 = 45,531,655
Notice both answers equal 45,531,655
With that explanation out of the way, let's continue. Next, we take the number 45,531,655 and divide it by 2:
45,531,655 ÷ 2 = 22,765,827.5
If the quotient is a whole number, then 2 and 22,765,827.5 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 | 45,531,655 | |
| -1 | -45,531,655 |
Now, we try dividing 45,531,655 by 3:
45,531,655 ÷ 3 = 15,177,218.3333
If the quotient is a whole number, then 3 and 15,177,218.3333 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 | 45,531,655 | |
| -1 | -45,531,655 |
Let's try dividing by 4:
45,531,655 ÷ 4 = 11,382,913.75
If the quotient is a whole number, then 4 and 11,382,913.75 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 | 45,531,655 | |
| -1 | 45,531,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 565 | 1,469 | 6,199 | 7,345 | 30,995 | 80,587 | 402,935 | 700,487 | 3,502,435 | 9,106,331 | 45,531,655 |
| -1 | -5 | -13 | -65 | -113 | -565 | -1,469 | -6,199 | -7,345 | -30,995 | -80,587 | -402,935 | -700,487 | -3,502,435 | -9,106,331 | -45,531,655 |
