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 69,447,223, 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 | 69,447,223 | |
| -1 | -69,447,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,447,223.
Example:
1 x 69,447,223 = 69,447,223
and
-1 x -69,447,223 = 69,447,223
Notice both answers equal 69,447,223
With that explanation out of the way, let's continue. Next, we take the number 69,447,223 and divide it by 2:
69,447,223 ÷ 2 = 34,723,611.5
If the quotient is a whole number, then 2 and 34,723,611.5 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 | 69,447,223 | |
| -1 | -69,447,223 |
Now, we try dividing 69,447,223 by 3:
69,447,223 ÷ 3 = 23,149,074.3333
If the quotient is a whole number, then 3 and 23,149,074.3333 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 | 69,447,223 | |
| -1 | -69,447,223 |
Let's try dividing by 4:
69,447,223 ÷ 4 = 17,361,805.75
If the quotient is a whole number, then 4 and 17,361,805.75 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 | 69,447,223 | |
| -1 | 69,447,223 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 157 | 589 | 751 | 2,983 | 4,867 | 14,269 | 23,281 | 92,473 | 117,907 | 442,339 | 2,240,233 | 3,655,117 | 69,447,223 |
| -1 | -19 | -31 | -157 | -589 | -751 | -2,983 | -4,867 | -14,269 | -23,281 | -92,473 | -117,907 | -442,339 | -2,240,233 | -3,655,117 | -69,447,223 |
