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 45,415,045, 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 | 45,415,045 | |
| -1 | -45,415,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,415,045.
Example:
1 x 45,415,045 = 45,415,045
and
-1 x -45,415,045 = 45,415,045
Notice both answers equal 45,415,045
With that explanation out of the way, let's continue. Next, we take the number 45,415,045 and divide it by 2:
45,415,045 ÷ 2 = 22,707,522.5
If the quotient is a whole number, then 2 and 22,707,522.5 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 | 45,415,045 | |
| -1 | -45,415,045 |
Now, we try dividing 45,415,045 by 3:
45,415,045 ÷ 3 = 15,138,348.3333
If the quotient is a whole number, then 3 and 15,138,348.3333 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 | 45,415,045 | |
| -1 | -45,415,045 |
Let's try dividing by 4:
45,415,045 ÷ 4 = 11,353,761.25
If the quotient is a whole number, then 4 and 11,353,761.25 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 | 45,415,045 | |
| -1 | 45,415,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 491 | 1,423 | 2,455 | 6,383 | 7,115 | 18,499 | 31,915 | 92,495 | 698,693 | 3,493,465 | 9,083,009 | 45,415,045 |
| -1 | -5 | -13 | -65 | -491 | -1,423 | -2,455 | -6,383 | -7,115 | -18,499 | -31,915 | -92,495 | -698,693 | -3,493,465 | -9,083,009 | -45,415,045 |
