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 64,132,201, 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 | 64,132,201 | |
| -1 | -64,132,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,132,201.
Example:
1 x 64,132,201 = 64,132,201
and
-1 x -64,132,201 = 64,132,201
Notice both answers equal 64,132,201
With that explanation out of the way, let's continue. Next, we take the number 64,132,201 and divide it by 2:
64,132,201 ÷ 2 = 32,066,100.5
If the quotient is a whole number, then 2 and 32,066,100.5 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 | 64,132,201 | |
| -1 | -64,132,201 |
Now, we try dividing 64,132,201 by 3:
64,132,201 ÷ 3 = 21,377,400.3333
If the quotient is a whole number, then 3 and 21,377,400.3333 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 | 64,132,201 | |
| -1 | -64,132,201 |
Let's try dividing by 4:
64,132,201 ÷ 4 = 16,033,050.25
If the quotient is a whole number, then 4 and 16,033,050.25 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 | 64,132,201 | |
| -1 | 64,132,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 383 | 1,259 | 2,681 | 7,277 | 8,813 | 23,921 | 50,939 | 167,447 | 482,197 | 3,375,379 | 9,161,743 | 64,132,201 |
| -1 | -7 | -19 | -133 | -383 | -1,259 | -2,681 | -7,277 | -8,813 | -23,921 | -50,939 | -167,447 | -482,197 | -3,375,379 | -9,161,743 | -64,132,201 |
