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 7,272,925, 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 | 7,272,925 | |
| -1 | -7,272,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,272,925.
Example:
1 x 7,272,925 = 7,272,925
and
-1 x -7,272,925 = 7,272,925
Notice both answers equal 7,272,925
With that explanation out of the way, let's continue. Next, we take the number 7,272,925 and divide it by 2:
7,272,925 ÷ 2 = 3,636,462.5
If the quotient is a whole number, then 2 and 3,636,462.5 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 | 7,272,925 | |
| -1 | -7,272,925 |
Now, we try dividing 7,272,925 by 3:
7,272,925 ÷ 3 = 2,424,308.3333
If the quotient is a whole number, then 3 and 2,424,308.3333 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 | 7,272,925 | |
| -1 | -7,272,925 |
Let's try dividing by 4:
7,272,925 ÷ 4 = 1,818,231.25
If the quotient is a whole number, then 4 and 1,818,231.25 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 | 7,272,925 | |
| -1 | 7,272,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 53 | 55 | 265 | 275 | 499 | 583 | 1,325 | 2,495 | 2,915 | 5,489 | 12,475 | 14,575 | 26,447 | 27,445 | 132,235 | 137,225 | 290,917 | 661,175 | 1,454,585 | 7,272,925 |
| -1 | -5 | -11 | -25 | -53 | -55 | -265 | -275 | -499 | -583 | -1,325 | -2,495 | -2,915 | -5,489 | -12,475 | -14,575 | -26,447 | -27,445 | -132,235 | -137,225 | -290,917 | -661,175 | -1,454,585 | -7,272,925 |
