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 7,716,275, 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 | 7,716,275 | |
| -1 | -7,716,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,716,275.
Example:
1 x 7,716,275 = 7,716,275
and
-1 x -7,716,275 = 7,716,275
Notice both answers equal 7,716,275
With that explanation out of the way, let's continue. Next, we take the number 7,716,275 and divide it by 2:
7,716,275 ÷ 2 = 3,858,137.5
If the quotient is a whole number, then 2 and 3,858,137.5 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 | 7,716,275 | |
| -1 | -7,716,275 |
Now, we try dividing 7,716,275 by 3:
7,716,275 ÷ 3 = 2,572,091.6667
If the quotient is a whole number, then 3 and 2,572,091.6667 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 | 7,716,275 | |
| -1 | -7,716,275 |
Let's try dividing by 4:
7,716,275 ÷ 4 = 1,929,068.75
If the quotient is a whole number, then 4 and 1,929,068.75 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 | 7,716,275 | |
| -1 | 7,716,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 6,299 | 31,495 | 44,093 | 157,475 | 220,465 | 308,651 | 1,102,325 | 1,543,255 | 7,716,275 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -6,299 | -31,495 | -44,093 | -157,475 | -220,465 | -308,651 | -1,102,325 | -1,543,255 | -7,716,275 |
