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 7,263,145, 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 | 7,263,145 | |
| -1 | -7,263,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,263,145.
Example:
1 x 7,263,145 = 7,263,145
and
-1 x -7,263,145 = 7,263,145
Notice both answers equal 7,263,145
With that explanation out of the way, let's continue. Next, we take the number 7,263,145 and divide it by 2:
7,263,145 ÷ 2 = 3,631,572.5
If the quotient is a whole number, then 2 and 3,631,572.5 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 | 7,263,145 | |
| -1 | -7,263,145 |
Now, we try dividing 7,263,145 by 3:
7,263,145 ÷ 3 = 2,421,048.3333
If the quotient is a whole number, then 3 and 2,421,048.3333 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 | 7,263,145 | |
| -1 | -7,263,145 |
Let's try dividing by 4:
7,263,145 ÷ 4 = 1,815,786.25
If the quotient is a whole number, then 4 and 1,815,786.25 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 | 7,263,145 | |
| -1 | 7,263,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 235 | 997 | 1,457 | 4,985 | 7,285 | 30,907 | 46,859 | 154,535 | 234,295 | 1,452,629 | 7,263,145 |
| -1 | -5 | -31 | -47 | -155 | -235 | -997 | -1,457 | -4,985 | -7,285 | -30,907 | -46,859 | -154,535 | -234,295 | -1,452,629 | -7,263,145 |
