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 7,637,539, 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 | 7,637,539 | |
| -1 | -7,637,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,637,539.
Example:
1 x 7,637,539 = 7,637,539
and
-1 x -7,637,539 = 7,637,539
Notice both answers equal 7,637,539
With that explanation out of the way, let's continue. Next, we take the number 7,637,539 and divide it by 2:
7,637,539 ÷ 2 = 3,818,769.5
If the quotient is a whole number, then 2 and 3,818,769.5 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 | 7,637,539 | |
| -1 | -7,637,539 |
Now, we try dividing 7,637,539 by 3:
7,637,539 ÷ 3 = 2,545,846.3333
If the quotient is a whole number, then 3 and 2,545,846.3333 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 | 7,637,539 | |
| -1 | -7,637,539 |
Let's try dividing by 4:
7,637,539 ÷ 4 = 1,909,384.75
If the quotient is a whole number, then 4 and 1,909,384.75 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 | 7,637,539 | |
| -1 | 7,637,539 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 4,937 | 34,559 | 64,181 | 83,929 | 449,267 | 587,503 | 1,091,077 | 7,637,539 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -4,937 | -34,559 | -64,181 | -83,929 | -449,267 | -587,503 | -1,091,077 | -7,637,539 |
