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 7,524,803, 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 | 7,524,803 | |
| -1 | -7,524,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,524,803.
Example:
1 x 7,524,803 = 7,524,803
and
-1 x -7,524,803 = 7,524,803
Notice both answers equal 7,524,803
With that explanation out of the way, let's continue. Next, we take the number 7,524,803 and divide it by 2:
7,524,803 ÷ 2 = 3,762,401.5
If the quotient is a whole number, then 2 and 3,762,401.5 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 | 7,524,803 | |
| -1 | -7,524,803 |
Now, we try dividing 7,524,803 by 3:
7,524,803 ÷ 3 = 2,508,267.6667
If the quotient is a whole number, then 3 and 2,508,267.6667 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 | 7,524,803 | |
| -1 | -7,524,803 |
Let's try dividing by 4:
7,524,803 ÷ 4 = 1,881,200.75
If the quotient is a whole number, then 4 and 1,881,200.75 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 | 7,524,803 | |
| -1 | 7,524,803 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 101 | 143 | 521 | 1,111 | 1,313 | 5,731 | 6,773 | 14,443 | 52,621 | 74,503 | 578,831 | 684,073 | 7,524,803 |
| -1 | -11 | -13 | -101 | -143 | -521 | -1,111 | -1,313 | -5,731 | -6,773 | -14,443 | -52,621 | -74,503 | -578,831 | -684,073 | -7,524,803 |
