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 64,626,133, 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 | 64,626,133 | |
| -1 | -64,626,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,626,133.
Example:
1 x 64,626,133 = 64,626,133
and
-1 x -64,626,133 = 64,626,133
Notice both answers equal 64,626,133
With that explanation out of the way, let's continue. Next, we take the number 64,626,133 and divide it by 2:
64,626,133 ÷ 2 = 32,313,066.5
If the quotient is a whole number, then 2 and 32,313,066.5 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 | 64,626,133 | |
| -1 | -64,626,133 |
Now, we try dividing 64,626,133 by 3:
64,626,133 ÷ 3 = 21,542,044.3333
If the quotient is a whole number, then 3 and 21,542,044.3333 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 | 64,626,133 | |
| -1 | -64,626,133 |
Let's try dividing by 4:
64,626,133 ÷ 4 = 16,156,533.25
If the quotient is a whole number, then 4 and 16,156,533.25 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 | 64,626,133 | |
| -1 | 64,626,133 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 53 | 143 | 583 | 689 | 7,579 | 8,527 | 93,797 | 110,851 | 451,931 | 1,219,361 | 4,971,241 | 5,875,103 | 64,626,133 |
| -1 | -11 | -13 | -53 | -143 | -583 | -689 | -7,579 | -8,527 | -93,797 | -110,851 | -451,931 | -1,219,361 | -4,971,241 | -5,875,103 | -64,626,133 |
