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 45,030,415, 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 | 45,030,415 | |
| -1 | -45,030,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,030,415.
Example:
1 x 45,030,415 = 45,030,415
and
-1 x -45,030,415 = 45,030,415
Notice both answers equal 45,030,415
With that explanation out of the way, let's continue. Next, we take the number 45,030,415 and divide it by 2:
45,030,415 ÷ 2 = 22,515,207.5
If the quotient is a whole number, then 2 and 22,515,207.5 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 | 45,030,415 | |
| -1 | -45,030,415 |
Now, we try dividing 45,030,415 by 3:
45,030,415 ÷ 3 = 15,010,138.3333
If the quotient is a whole number, then 3 and 15,010,138.3333 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 | 45,030,415 | |
| -1 | -45,030,415 |
Let's try dividing by 4:
45,030,415 ÷ 4 = 11,257,603.75
If the quotient is a whole number, then 4 and 11,257,603.75 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 | 45,030,415 | |
| -1 | 45,030,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 107 | 365 | 535 | 1,153 | 5,765 | 7,811 | 39,055 | 84,169 | 123,371 | 420,845 | 616,855 | 9,006,083 | 45,030,415 |
| -1 | -5 | -73 | -107 | -365 | -535 | -1,153 | -5,765 | -7,811 | -39,055 | -84,169 | -123,371 | -420,845 | -616,855 | -9,006,083 | -45,030,415 |
