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 45,704,545, 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 | 45,704,545 | |
| -1 | -45,704,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,704,545.
Example:
1 x 45,704,545 = 45,704,545
and
-1 x -45,704,545 = 45,704,545
Notice both answers equal 45,704,545
With that explanation out of the way, let's continue. Next, we take the number 45,704,545 and divide it by 2:
45,704,545 ÷ 2 = 22,852,272.5
If the quotient is a whole number, then 2 and 22,852,272.5 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 | 45,704,545 | |
| -1 | -45,704,545 |
Now, we try dividing 45,704,545 by 3:
45,704,545 ÷ 3 = 15,234,848.3333
If the quotient is a whole number, then 3 and 15,234,848.3333 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 | 45,704,545 | |
| -1 | -45,704,545 |
Let's try dividing by 4:
45,704,545 ÷ 4 = 11,426,136.25
If the quotient is a whole number, then 4 and 11,426,136.25 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 | 45,704,545 | |
| -1 | 45,704,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 113 | 205 | 565 | 1,973 | 4,633 | 9,865 | 23,165 | 80,893 | 222,949 | 404,465 | 1,114,745 | 9,140,909 | 45,704,545 |
| -1 | -5 | -41 | -113 | -205 | -565 | -1,973 | -4,633 | -9,865 | -23,165 | -80,893 | -222,949 | -404,465 | -1,114,745 | -9,140,909 | -45,704,545 |
