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 7,235,875, 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 | 7,235,875 | |
| -1 | -7,235,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,235,875.
Example:
1 x 7,235,875 = 7,235,875
and
-1 x -7,235,875 = 7,235,875
Notice both answers equal 7,235,875
With that explanation out of the way, let's continue. Next, we take the number 7,235,875 and divide it by 2:
7,235,875 ÷ 2 = 3,617,937.5
If the quotient is a whole number, then 2 and 3,617,937.5 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 | 7,235,875 | |
| -1 | -7,235,875 |
Now, we try dividing 7,235,875 by 3:
7,235,875 ÷ 3 = 2,411,958.3333
If the quotient is a whole number, then 3 and 2,411,958.3333 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 | 7,235,875 | |
| -1 | -7,235,875 |
Let's try dividing by 4:
7,235,875 ÷ 4 = 1,808,968.75
If the quotient is a whole number, then 4 and 1,808,968.75 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 | 7,235,875 | |
| -1 | 7,235,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 107 | 125 | 535 | 541 | 2,675 | 2,705 | 13,375 | 13,525 | 57,887 | 67,625 | 289,435 | 1,447,175 | 7,235,875 |
| -1 | -5 | -25 | -107 | -125 | -535 | -541 | -2,675 | -2,705 | -13,375 | -13,525 | -57,887 | -67,625 | -289,435 | -1,447,175 | -7,235,875 |
