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 5,153,225, 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 | 5,153,225 | |
| -1 | -5,153,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,153,225.
Example:
1 x 5,153,225 = 5,153,225
and
-1 x -5,153,225 = 5,153,225
Notice both answers equal 5,153,225
With that explanation out of the way, let's continue. Next, we take the number 5,153,225 and divide it by 2:
5,153,225 ÷ 2 = 2,576,612.5
If the quotient is a whole number, then 2 and 2,576,612.5 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 | 5,153,225 | |
| -1 | -5,153,225 |
Now, we try dividing 5,153,225 by 3:
5,153,225 ÷ 3 = 1,717,741.6667
If the quotient is a whole number, then 3 and 1,717,741.6667 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 | 5,153,225 | |
| -1 | -5,153,225 |
Let's try dividing by 4:
5,153,225 ÷ 4 = 1,288,306.25
If the quotient is a whole number, then 4 and 1,288,306.25 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 | 5,153,225 | |
| -1 | 5,153,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 2,677 | 13,385 | 18,739 | 29,447 | 66,925 | 93,695 | 147,235 | 206,129 | 468,475 | 736,175 | 1,030,645 | 5,153,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -2,677 | -13,385 | -18,739 | -29,447 | -66,925 | -93,695 | -147,235 | -206,129 | -468,475 | -736,175 | -1,030,645 | -5,153,225 |
