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 7,234,075, 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 | 7,234,075 | |
| -1 | -7,234,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,234,075.
Example:
1 x 7,234,075 = 7,234,075
and
-1 x -7,234,075 = 7,234,075
Notice both answers equal 7,234,075
With that explanation out of the way, let's continue. Next, we take the number 7,234,075 and divide it by 2:
7,234,075 ÷ 2 = 3,617,037.5
If the quotient is a whole number, then 2 and 3,617,037.5 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 | 7,234,075 | |
| -1 | -7,234,075 |
Now, we try dividing 7,234,075 by 3:
7,234,075 ÷ 3 = 2,411,358.3333
If the quotient is a whole number, then 3 and 2,411,358.3333 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 | 7,234,075 | |
| -1 | -7,234,075 |
Let's try dividing by 4:
7,234,075 ÷ 4 = 1,808,518.75
If the quotient is a whole number, then 4 and 1,808,518.75 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 | 7,234,075 | |
| -1 | 7,234,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 529 | 547 | 575 | 2,645 | 2,735 | 12,581 | 13,225 | 13,675 | 62,905 | 289,363 | 314,525 | 1,446,815 | 7,234,075 |
| -1 | -5 | -23 | -25 | -115 | -529 | -547 | -575 | -2,645 | -2,735 | -12,581 | -13,225 | -13,675 | -62,905 | -289,363 | -314,525 | -1,446,815 | -7,234,075 |
