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 7,520,879, 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 | 7,520,879 | |
| -1 | -7,520,879 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,520,879.
Example:
1 x 7,520,879 = 7,520,879
and
-1 x -7,520,879 = 7,520,879
Notice both answers equal 7,520,879
With that explanation out of the way, let's continue. Next, we take the number 7,520,879 and divide it by 2:
7,520,879 ÷ 2 = 3,760,439.5
If the quotient is a whole number, then 2 and 3,760,439.5 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 | 7,520,879 | |
| -1 | -7,520,879 |
Now, we try dividing 7,520,879 by 3:
7,520,879 ÷ 3 = 2,506,959.6667
If the quotient is a whole number, then 3 and 2,506,959.6667 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 | 7,520,879 | |
| -1 | -7,520,879 |
Let's try dividing by 4:
7,520,879 ÷ 4 = 1,880,219.75
If the quotient is a whole number, then 4 and 1,880,219.75 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 | 7,520,879 | |
| -1 | 7,520,879 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 79 | 83 | 1,147 | 2,449 | 2,573 | 2,923 | 3,071 | 6,557 | 90,613 | 95,201 | 203,267 | 242,609 | 7,520,879 |
| -1 | -31 | -37 | -79 | -83 | -1,147 | -2,449 | -2,573 | -2,923 | -3,071 | -6,557 | -90,613 | -95,201 | -203,267 | -242,609 | -7,520,879 |
