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 7,151,095, 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 | 7,151,095 | |
| -1 | -7,151,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,151,095.
Example:
1 x 7,151,095 = 7,151,095
and
-1 x -7,151,095 = 7,151,095
Notice both answers equal 7,151,095
With that explanation out of the way, let's continue. Next, we take the number 7,151,095 and divide it by 2:
7,151,095 ÷ 2 = 3,575,547.5
If the quotient is a whole number, then 2 and 3,575,547.5 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 | 7,151,095 | |
| -1 | -7,151,095 |
Now, we try dividing 7,151,095 by 3:
7,151,095 ÷ 3 = 2,383,698.3333
If the quotient is a whole number, then 3 and 2,383,698.3333 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 | 7,151,095 | |
| -1 | -7,151,095 |
Let's try dividing by 4:
7,151,095 ÷ 4 = 1,787,773.75
If the quotient is a whole number, then 4 and 1,787,773.75 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 | 7,151,095 | |
| -1 | 7,151,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 3,463 | 17,315 | 24,241 | 121,205 | 204,317 | 1,021,585 | 1,430,219 | 7,151,095 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -3,463 | -17,315 | -24,241 | -121,205 | -204,317 | -1,021,585 | -1,430,219 | -7,151,095 |
