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 45,042,845, 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 | 45,042,845 | |
| -1 | -45,042,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,042,845.
Example:
1 x 45,042,845 = 45,042,845
and
-1 x -45,042,845 = 45,042,845
Notice both answers equal 45,042,845
With that explanation out of the way, let's continue. Next, we take the number 45,042,845 and divide it by 2:
45,042,845 ÷ 2 = 22,521,422.5
If the quotient is a whole number, then 2 and 22,521,422.5 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 | 45,042,845 | |
| -1 | -45,042,845 |
Now, we try dividing 45,042,845 by 3:
45,042,845 ÷ 3 = 15,014,281.6667
If the quotient is a whole number, then 3 and 15,014,281.6667 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 | 45,042,845 | |
| -1 | -45,042,845 |
Let's try dividing by 4:
45,042,845 ÷ 4 = 11,260,711.25
If the quotient is a whole number, then 4 and 11,260,711.25 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 | 45,042,845 | |
| -1 | 45,042,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 53 | 155 | 265 | 1,643 | 5,483 | 8,215 | 27,415 | 169,973 | 290,599 | 849,865 | 1,452,995 | 9,008,569 | 45,042,845 |
| -1 | -5 | -31 | -53 | -155 | -265 | -1,643 | -5,483 | -8,215 | -27,415 | -169,973 | -290,599 | -849,865 | -1,452,995 | -9,008,569 | -45,042,845 |
