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 9,290,279, 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 | 9,290,279 | |
| -1 | -9,290,279 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,290,279.
Example:
1 x 9,290,279 = 9,290,279
and
-1 x -9,290,279 = 9,290,279
Notice both answers equal 9,290,279
With that explanation out of the way, let's continue. Next, we take the number 9,290,279 and divide it by 2:
9,290,279 ÷ 2 = 4,645,139.5
If the quotient is a whole number, then 2 and 4,645,139.5 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 | 9,290,279 | |
| -1 | -9,290,279 |
Now, we try dividing 9,290,279 by 3:
9,290,279 ÷ 3 = 3,096,759.6667
If the quotient is a whole number, then 3 and 3,096,759.6667 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 | 9,290,279 | |
| -1 | -9,290,279 |
Let's try dividing by 4:
9,290,279 ÷ 4 = 2,322,569.75
If the quotient is a whole number, then 4 and 2,322,569.75 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 | 9,290,279 | |
| -1 | 9,290,279 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 71 | 179 | 731 | 1,207 | 3,043 | 3,053 | 7,697 | 12,709 | 51,901 | 130,849 | 216,053 | 546,487 | 9,290,279 |
| -1 | -17 | -43 | -71 | -179 | -731 | -1,207 | -3,043 | -3,053 | -7,697 | -12,709 | -51,901 | -130,849 | -216,053 | -546,487 | -9,290,279 |
