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 13,422,367, 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 | 13,422,367 | |
| -1 | -13,422,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,422,367.
Example:
1 x 13,422,367 = 13,422,367
and
-1 x -13,422,367 = 13,422,367
Notice both answers equal 13,422,367
With that explanation out of the way, let's continue. Next, we take the number 13,422,367 and divide it by 2:
13,422,367 ÷ 2 = 6,711,183.5
If the quotient is a whole number, then 2 and 6,711,183.5 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 | 13,422,367 | |
| -1 | -13,422,367 |
Now, we try dividing 13,422,367 by 3:
13,422,367 ÷ 3 = 4,474,122.3333
If the quotient is a whole number, then 3 and 4,474,122.3333 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 | 13,422,367 | |
| -1 | -13,422,367 |
Let's try dividing by 4:
13,422,367 ÷ 4 = 3,355,591.75
If the quotient is a whole number, then 4 and 3,355,591.75 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 | 13,422,367 | |
| -1 | 13,422,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 149 | 757 | 1,043 | 2,533 | 5,299 | 12,869 | 17,731 | 90,083 | 112,793 | 789,551 | 1,917,481 | 13,422,367 |
| -1 | -7 | -17 | -119 | -149 | -757 | -1,043 | -2,533 | -5,299 | -12,869 | -17,731 | -90,083 | -112,793 | -789,551 | -1,917,481 | -13,422,367 |
