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 5,474,197, 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 | 5,474,197 | |
| -1 | -5,474,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,474,197.
Example:
1 x 5,474,197 = 5,474,197
and
-1 x -5,474,197 = 5,474,197
Notice both answers equal 5,474,197
With that explanation out of the way, let's continue. Next, we take the number 5,474,197 and divide it by 2:
5,474,197 ÷ 2 = 2,737,098.5
If the quotient is a whole number, then 2 and 2,737,098.5 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 | 5,474,197 | |
| -1 | -5,474,197 |
Now, we try dividing 5,474,197 by 3:
5,474,197 ÷ 3 = 1,824,732.3333
If the quotient is a whole number, then 3 and 1,824,732.3333 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 | 5,474,197 | |
| -1 | -5,474,197 |
Let's try dividing by 4:
5,474,197 ÷ 4 = 1,368,549.25
If the quotient is a whole number, then 4 and 1,368,549.25 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 | 5,474,197 | |
| -1 | 5,474,197 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 59 | 73 | 1,271 | 1,829 | 2,263 | 2,419 | 2,993 | 4,307 | 74,989 | 92,783 | 133,517 | 176,587 | 5,474,197 |
| -1 | -31 | -41 | -59 | -73 | -1,271 | -1,829 | -2,263 | -2,419 | -2,993 | -4,307 | -74,989 | -92,783 | -133,517 | -176,587 | -5,474,197 |
