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 67,552,513, 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 | 67,552,513 | |
| -1 | -67,552,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,552,513.
Example:
1 x 67,552,513 = 67,552,513
and
-1 x -67,552,513 = 67,552,513
Notice both answers equal 67,552,513
With that explanation out of the way, let's continue. Next, we take the number 67,552,513 and divide it by 2:
67,552,513 ÷ 2 = 33,776,256.5
If the quotient is a whole number, then 2 and 33,776,256.5 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 | 67,552,513 | |
| -1 | -67,552,513 |
Now, we try dividing 67,552,513 by 3:
67,552,513 ÷ 3 = 22,517,504.3333
If the quotient is a whole number, then 3 and 22,517,504.3333 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 | 67,552,513 | |
| -1 | -67,552,513 |
Let's try dividing by 4:
67,552,513 ÷ 4 = 16,888,128.25
If the quotient is a whole number, then 4 and 16,888,128.25 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 | 67,552,513 | |
| -1 | 67,552,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 89 | 203 | 623 | 2,581 | 3,739 | 18,067 | 26,173 | 108,431 | 332,771 | 759,017 | 2,329,397 | 9,650,359 | 67,552,513 |
| -1 | -7 | -29 | -89 | -203 | -623 | -2,581 | -3,739 | -18,067 | -26,173 | -108,431 | -332,771 | -759,017 | -2,329,397 | -9,650,359 | -67,552,513 |
