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 7,474,961, 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 | 7,474,961 | |
| -1 | -7,474,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,474,961.
Example:
1 x 7,474,961 = 7,474,961
and
-1 x -7,474,961 = 7,474,961
Notice both answers equal 7,474,961
With that explanation out of the way, let's continue. Next, we take the number 7,474,961 and divide it by 2:
7,474,961 ÷ 2 = 3,737,480.5
If the quotient is a whole number, then 2 and 3,737,480.5 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 | 7,474,961 | |
| -1 | -7,474,961 |
Now, we try dividing 7,474,961 by 3:
7,474,961 ÷ 3 = 2,491,653.6667
If the quotient is a whole number, then 3 and 2,491,653.6667 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 | 7,474,961 | |
| -1 | -7,474,961 |
Let's try dividing by 4:
7,474,961 ÷ 4 = 1,868,740.25
If the quotient is a whole number, then 4 and 1,868,740.25 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 | 7,474,961 | |
| -1 | 7,474,961 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 53 | 247 | 571 | 689 | 1,007 | 7,423 | 10,849 | 13,091 | 30,263 | 141,037 | 393,419 | 574,997 | 7,474,961 |
| -1 | -13 | -19 | -53 | -247 | -571 | -689 | -1,007 | -7,423 | -10,849 | -13,091 | -30,263 | -141,037 | -393,419 | -574,997 | -7,474,961 |
