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 4,361,245, 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 | 4,361,245 | |
| -1 | -4,361,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,361,245.
Example:
1 x 4,361,245 = 4,361,245
and
-1 x -4,361,245 = 4,361,245
Notice both answers equal 4,361,245
With that explanation out of the way, let's continue. Next, we take the number 4,361,245 and divide it by 2:
4,361,245 ÷ 2 = 2,180,622.5
If the quotient is a whole number, then 2 and 2,180,622.5 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 | 4,361,245 | |
| -1 | -4,361,245 |
Now, we try dividing 4,361,245 by 3:
4,361,245 ÷ 3 = 1,453,748.3333
If the quotient is a whole number, then 3 and 1,453,748.3333 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 | 4,361,245 | |
| -1 | -4,361,245 |
Let's try dividing by 4:
4,361,245 ÷ 4 = 1,090,311.25
If the quotient is a whole number, then 4 and 1,090,311.25 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 | 4,361,245 | |
| -1 | 4,361,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 2,543 | 12,715 | 17,801 | 89,005 | 124,607 | 623,035 | 872,249 | 4,361,245 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -2,543 | -12,715 | -17,801 | -89,005 | -124,607 | -623,035 | -872,249 | -4,361,245 |
