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 2,245,345, 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 | 2,245,345 | |
| -1 | -2,245,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,245,345.
Example:
1 x 2,245,345 = 2,245,345
and
-1 x -2,245,345 = 2,245,345
Notice both answers equal 2,245,345
With that explanation out of the way, let's continue. Next, we take the number 2,245,345 and divide it by 2:
2,245,345 ÷ 2 = 1,122,672.5
If the quotient is a whole number, then 2 and 1,122,672.5 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 | 2,245,345 | |
| -1 | -2,245,345 |
Now, we try dividing 2,245,345 by 3:
2,245,345 ÷ 3 = 748,448.3333
If the quotient is a whole number, then 3 and 748,448.3333 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 | 2,245,345 | |
| -1 | -2,245,345 |
Let's try dividing by 4:
2,245,345 ÷ 4 = 561,336.25
If the quotient is a whole number, then 4 and 561,336.25 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 | 2,245,345 | |
| -1 | 2,245,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 53 | 185 | 229 | 265 | 1,145 | 1,961 | 8,473 | 9,805 | 12,137 | 42,365 | 60,685 | 449,069 | 2,245,345 |
| -1 | -5 | -37 | -53 | -185 | -229 | -265 | -1,145 | -1,961 | -8,473 | -9,805 | -12,137 | -42,365 | -60,685 | -449,069 | -2,245,345 |
