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 761,915, 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 | 761,915 | |
| -1 | -761,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,915.
Example:
1 x 761,915 = 761,915
and
-1 x -761,915 = 761,915
Notice both answers equal 761,915
With that explanation out of the way, let's continue. Next, we take the number 761,915 and divide it by 2:
761,915 ÷ 2 = 380,957.5
If the quotient is a whole number, then 2 and 380,957.5 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 | 761,915 | |
| -1 | -761,915 |
Now, we try dividing 761,915 by 3:
761,915 ÷ 3 = 253,971.6667
If the quotient is a whole number, then 3 and 253,971.6667 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 | 761,915 | |
| -1 | -761,915 |
Let's try dividing by 4:
761,915 ÷ 4 = 190,478.75
If the quotient is a whole number, then 4 and 190,478.75 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 | 761,915 | |
| -1 | 761,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 1,979 | 9,895 | 13,853 | 21,769 | 69,265 | 108,845 | 152,383 | 761,915 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -1,979 | -9,895 | -13,853 | -21,769 | -69,265 | -108,845 | -152,383 | -761,915 |
