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 5,611,645, 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 | 5,611,645 | |
| -1 | -5,611,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,611,645.
Example:
1 x 5,611,645 = 5,611,645
and
-1 x -5,611,645 = 5,611,645
Notice both answers equal 5,611,645
With that explanation out of the way, let's continue. Next, we take the number 5,611,645 and divide it by 2:
5,611,645 ÷ 2 = 2,805,822.5
If the quotient is a whole number, then 2 and 2,805,822.5 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 | 5,611,645 | |
| -1 | -5,611,645 |
Now, we try dividing 5,611,645 by 3:
5,611,645 ÷ 3 = 1,870,548.3333
If the quotient is a whole number, then 3 and 1,870,548.3333 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 | 5,611,645 | |
| -1 | -5,611,645 |
Let's try dividing by 4:
5,611,645 ÷ 4 = 1,402,911.25
If the quotient is a whole number, then 4 and 1,402,911.25 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 | 5,611,645 | |
| -1 | 5,611,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 169 | 229 | 377 | 845 | 1,145 | 1,885 | 2,977 | 4,901 | 6,641 | 14,885 | 24,505 | 33,205 | 38,701 | 86,333 | 193,505 | 431,665 | 1,122,329 | 5,611,645 |
| -1 | -5 | -13 | -29 | -65 | -145 | -169 | -229 | -377 | -845 | -1,145 | -1,885 | -2,977 | -4,901 | -6,641 | -14,885 | -24,505 | -33,205 | -38,701 | -86,333 | -193,505 | -431,665 | -1,122,329 | -5,611,645 |
