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 45,263,845, 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 | 45,263,845 | |
| -1 | -45,263,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,263,845.
Example:
1 x 45,263,845 = 45,263,845
and
-1 x -45,263,845 = 45,263,845
Notice both answers equal 45,263,845
With that explanation out of the way, let's continue. Next, we take the number 45,263,845 and divide it by 2:
45,263,845 ÷ 2 = 22,631,922.5
If the quotient is a whole number, then 2 and 22,631,922.5 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 | 45,263,845 | |
| -1 | -45,263,845 |
Now, we try dividing 45,263,845 by 3:
45,263,845 ÷ 3 = 15,087,948.3333
If the quotient is a whole number, then 3 and 15,087,948.3333 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 | 45,263,845 | |
| -1 | -45,263,845 |
Let's try dividing by 4:
45,263,845 ÷ 4 = 11,315,961.25
If the quotient is a whole number, then 4 and 11,315,961.25 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 | 45,263,845 | |
| -1 | 45,263,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 113 | 565 | 1,243 | 6,215 | 7,283 | 36,415 | 80,113 | 400,565 | 822,979 | 4,114,895 | 9,052,769 | 45,263,845 |
| -1 | -5 | -11 | -55 | -113 | -565 | -1,243 | -6,215 | -7,283 | -36,415 | -80,113 | -400,565 | -822,979 | -4,114,895 | -9,052,769 | -45,263,845 |
