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 7,610,005, 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 | 7,610,005 | |
| -1 | -7,610,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,610,005.
Example:
1 x 7,610,005 = 7,610,005
and
-1 x -7,610,005 = 7,610,005
Notice both answers equal 7,610,005
With that explanation out of the way, let's continue. Next, we take the number 7,610,005 and divide it by 2:
7,610,005 ÷ 2 = 3,805,002.5
If the quotient is a whole number, then 2 and 3,805,002.5 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 | 7,610,005 | |
| -1 | -7,610,005 |
Now, we try dividing 7,610,005 by 3:
7,610,005 ÷ 3 = 2,536,668.3333
If the quotient is a whole number, then 3 and 2,536,668.3333 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 | 7,610,005 | |
| -1 | -7,610,005 |
Let's try dividing by 4:
7,610,005 ÷ 4 = 1,902,501.25
If the quotient is a whole number, then 4 and 1,902,501.25 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 | 7,610,005 | |
| -1 | 7,610,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 53 | 65 | 235 | 265 | 611 | 689 | 2,209 | 2,491 | 3,055 | 3,445 | 11,045 | 12,455 | 28,717 | 32,383 | 117,077 | 143,585 | 161,915 | 585,385 | 1,522,001 | 7,610,005 |
| -1 | -5 | -13 | -47 | -53 | -65 | -235 | -265 | -611 | -689 | -2,209 | -2,491 | -3,055 | -3,445 | -11,045 | -12,455 | -28,717 | -32,383 | -117,077 | -143,585 | -161,915 | -585,385 | -1,522,001 | -7,610,005 |
