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 7,607,047, 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 | 7,607,047 | |
| -1 | -7,607,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,607,047.
Example:
1 x 7,607,047 = 7,607,047
and
-1 x -7,607,047 = 7,607,047
Notice both answers equal 7,607,047
With that explanation out of the way, let's continue. Next, we take the number 7,607,047 and divide it by 2:
7,607,047 ÷ 2 = 3,803,523.5
If the quotient is a whole number, then 2 and 3,803,523.5 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 | 7,607,047 | |
| -1 | -7,607,047 |
Now, we try dividing 7,607,047 by 3:
7,607,047 ÷ 3 = 2,535,682.3333
If the quotient is a whole number, then 3 and 2,535,682.3333 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 | 7,607,047 | |
| -1 | -7,607,047 |
Let's try dividing by 4:
7,607,047 ÷ 4 = 1,901,761.75
If the quotient is a whole number, then 4 and 1,901,761.75 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 | 7,607,047 | |
| -1 | 7,607,047 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 113 | 163 | 413 | 791 | 1,141 | 6,667 | 9,617 | 18,419 | 46,669 | 67,319 | 128,933 | 1,086,721 | 7,607,047 |
| -1 | -7 | -59 | -113 | -163 | -413 | -791 | -1,141 | -6,667 | -9,617 | -18,419 | -46,669 | -67,319 | -128,933 | -1,086,721 | -7,607,047 |
