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 64,123,553, 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 | 64,123,553 | |
| -1 | -64,123,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,123,553.
Example:
1 x 64,123,553 = 64,123,553
and
-1 x -64,123,553 = 64,123,553
Notice both answers equal 64,123,553
With that explanation out of the way, let's continue. Next, we take the number 64,123,553 and divide it by 2:
64,123,553 ÷ 2 = 32,061,776.5
If the quotient is a whole number, then 2 and 32,061,776.5 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 | 64,123,553 | |
| -1 | -64,123,553 |
Now, we try dividing 64,123,553 by 3:
64,123,553 ÷ 3 = 21,374,517.6667
If the quotient is a whole number, then 3 and 21,374,517.6667 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 | 64,123,553 | |
| -1 | -64,123,553 |
Let's try dividing by 4:
64,123,553 ÷ 4 = 16,030,888.25
If the quotient is a whole number, then 4 and 16,030,888.25 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 | 64,123,553 | |
| -1 | 64,123,553 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 37 | 377 | 481 | 1,073 | 4,597 | 13,949 | 59,761 | 133,313 | 170,089 | 1,733,069 | 2,211,157 | 4,932,581 | 64,123,553 |
| -1 | -13 | -29 | -37 | -377 | -481 | -1,073 | -4,597 | -13,949 | -59,761 | -133,313 | -170,089 | -1,733,069 | -2,211,157 | -4,932,581 | -64,123,553 |
