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 45,372,845, 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 | 45,372,845 | |
| -1 | -45,372,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,372,845.
Example:
1 x 45,372,845 = 45,372,845
and
-1 x -45,372,845 = 45,372,845
Notice both answers equal 45,372,845
With that explanation out of the way, let's continue. Next, we take the number 45,372,845 and divide it by 2:
45,372,845 ÷ 2 = 22,686,422.5
If the quotient is a whole number, then 2 and 22,686,422.5 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 | 45,372,845 | |
| -1 | -45,372,845 |
Now, we try dividing 45,372,845 by 3:
45,372,845 ÷ 3 = 15,124,281.6667
If the quotient is a whole number, then 3 and 15,124,281.6667 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 | 45,372,845 | |
| -1 | -45,372,845 |
Let's try dividing by 4:
45,372,845 ÷ 4 = 11,343,211.25
If the quotient is a whole number, then 4 and 11,343,211.25 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 | 45,372,845 | |
| -1 | 45,372,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 439 | 2,195 | 2,953 | 3,073 | 14,765 | 15,365 | 20,671 | 103,355 | 1,296,367 | 6,481,835 | 9,074,569 | 45,372,845 |
| -1 | -5 | -7 | -35 | -439 | -2,195 | -2,953 | -3,073 | -14,765 | -15,365 | -20,671 | -103,355 | -1,296,367 | -6,481,835 | -9,074,569 | -45,372,845 |
