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 7,537,705, 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 | 7,537,705 | |
| -1 | -7,537,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,537,705.
Example:
1 x 7,537,705 = 7,537,705
and
-1 x -7,537,705 = 7,537,705
Notice both answers equal 7,537,705
With that explanation out of the way, let's continue. Next, we take the number 7,537,705 and divide it by 2:
7,537,705 ÷ 2 = 3,768,852.5
If the quotient is a whole number, then 2 and 3,768,852.5 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 | 7,537,705 | |
| -1 | -7,537,705 |
Now, we try dividing 7,537,705 by 3:
7,537,705 ÷ 3 = 2,512,568.3333
If the quotient is a whole number, then 3 and 2,512,568.3333 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 | 7,537,705 | |
| -1 | -7,537,705 |
Let's try dividing by 4:
7,537,705 ÷ 4 = 1,884,426.25
If the quotient is a whole number, then 4 and 1,884,426.25 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 | 7,537,705 | |
| -1 | 7,537,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 283 | 761 | 1,415 | 1,981 | 3,805 | 5,327 | 9,905 | 26,635 | 215,363 | 1,076,815 | 1,507,541 | 7,537,705 |
| -1 | -5 | -7 | -35 | -283 | -761 | -1,415 | -1,981 | -3,805 | -5,327 | -9,905 | -26,635 | -215,363 | -1,076,815 | -1,507,541 | -7,537,705 |
