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 39,452,567, 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 | 39,452,567 | |
| -1 | -39,452,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,452,567.
Example:
1 x 39,452,567 = 39,452,567
and
-1 x -39,452,567 = 39,452,567
Notice both answers equal 39,452,567
With that explanation out of the way, let's continue. Next, we take the number 39,452,567 and divide it by 2:
39,452,567 ÷ 2 = 19,726,283.5
If the quotient is a whole number, then 2 and 19,726,283.5 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 | 39,452,567 | |
| -1 | -39,452,567 |
Now, we try dividing 39,452,567 by 3:
39,452,567 ÷ 3 = 13,150,855.6667
If the quotient is a whole number, then 3 and 13,150,855.6667 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 | 39,452,567 | |
| -1 | -39,452,567 |
Let's try dividing by 4:
39,452,567 ÷ 4 = 9,863,141.75
If the quotient is a whole number, then 4 and 9,863,141.75 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 | 39,452,567 | |
| -1 | 39,452,567 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 22,277 | 155,939 | 245,047 | 512,371 | 1,715,329 | 3,586,597 | 5,636,081 | 39,452,567 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -22,277 | -155,939 | -245,047 | -512,371 | -1,715,329 | -3,586,597 | -5,636,081 | -39,452,567 |
