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 45,091,067, 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 | 45,091,067 | |
| -1 | -45,091,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,091,067.
Example:
1 x 45,091,067 = 45,091,067
and
-1 x -45,091,067 = 45,091,067
Notice both answers equal 45,091,067
With that explanation out of the way, let's continue. Next, we take the number 45,091,067 and divide it by 2:
45,091,067 ÷ 2 = 22,545,533.5
If the quotient is a whole number, then 2 and 22,545,533.5 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 | 45,091,067 | |
| -1 | -45,091,067 |
Now, we try dividing 45,091,067 by 3:
45,091,067 ÷ 3 = 15,030,355.6667
If the quotient is a whole number, then 3 and 15,030,355.6667 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 | 45,091,067 | |
| -1 | -45,091,067 |
Let's try dividing by 4:
45,091,067 ÷ 4 = 11,272,766.75
If the quotient is a whole number, then 4 and 11,272,766.75 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 | 45,091,067 | |
| -1 | 45,091,067 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 79 | 469 | 553 | 1,217 | 5,293 | 8,519 | 37,051 | 81,539 | 96,143 | 570,773 | 673,001 | 6,441,581 | 45,091,067 |
| -1 | -7 | -67 | -79 | -469 | -553 | -1,217 | -5,293 | -8,519 | -37,051 | -81,539 | -96,143 | -570,773 | -673,001 | -6,441,581 | -45,091,067 |
