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 2,957,915, 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 | 2,957,915 | |
| -1 | -2,957,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,957,915.
Example:
1 x 2,957,915 = 2,957,915
and
-1 x -2,957,915 = 2,957,915
Notice both answers equal 2,957,915
With that explanation out of the way, let's continue. Next, we take the number 2,957,915 and divide it by 2:
2,957,915 ÷ 2 = 1,478,957.5
If the quotient is a whole number, then 2 and 1,478,957.5 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 | 2,957,915 | |
| -1 | -2,957,915 |
Now, we try dividing 2,957,915 by 3:
2,957,915 ÷ 3 = 985,971.6667
If the quotient is a whole number, then 3 and 985,971.6667 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 | 2,957,915 | |
| -1 | -2,957,915 |
Let's try dividing by 4:
2,957,915 ÷ 4 = 739,478.75
If the quotient is a whole number, then 4 and 739,478.75 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 | 2,957,915 | |
| -1 | 2,957,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 89 | 115 | 289 | 391 | 445 | 1,445 | 1,513 | 1,955 | 2,047 | 6,647 | 7,565 | 10,235 | 25,721 | 33,235 | 34,799 | 128,605 | 173,995 | 591,583 | 2,957,915 |
| -1 | -5 | -17 | -23 | -85 | -89 | -115 | -289 | -391 | -445 | -1,445 | -1,513 | -1,955 | -2,047 | -6,647 | -7,565 | -10,235 | -25,721 | -33,235 | -34,799 | -128,605 | -173,995 | -591,583 | -2,957,915 |
