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 7,542,577, 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 | 7,542,577 | |
| -1 | -7,542,577 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,542,577.
Example:
1 x 7,542,577 = 7,542,577
and
-1 x -7,542,577 = 7,542,577
Notice both answers equal 7,542,577
With that explanation out of the way, let's continue. Next, we take the number 7,542,577 and divide it by 2:
7,542,577 ÷ 2 = 3,771,288.5
If the quotient is a whole number, then 2 and 3,771,288.5 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 | 7,542,577 | |
| -1 | -7,542,577 |
Now, we try dividing 7,542,577 by 3:
7,542,577 ÷ 3 = 2,514,192.3333
If the quotient is a whole number, then 3 and 2,514,192.3333 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 | 7,542,577 | |
| -1 | -7,542,577 |
Let's try dividing by 4:
7,542,577 ÷ 4 = 1,885,644.25
If the quotient is a whole number, then 4 and 1,885,644.25 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 | 7,542,577 | |
| -1 | 7,542,577 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 241 | 263 | 1,687 | 1,841 | 4,097 | 4,471 | 28,679 | 31,297 | 63,383 | 443,681 | 1,077,511 | 7,542,577 |
| -1 | -7 | -17 | -119 | -241 | -263 | -1,687 | -1,841 | -4,097 | -4,471 | -28,679 | -31,297 | -63,383 | -443,681 | -1,077,511 | -7,542,577 |
