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 64,832,131, 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 | 64,832,131 | |
| -1 | -64,832,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,832,131.
Example:
1 x 64,832,131 = 64,832,131
and
-1 x -64,832,131 = 64,832,131
Notice both answers equal 64,832,131
With that explanation out of the way, let's continue. Next, we take the number 64,832,131 and divide it by 2:
64,832,131 ÷ 2 = 32,416,065.5
If the quotient is a whole number, then 2 and 32,416,065.5 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 | 64,832,131 | |
| -1 | -64,832,131 |
Now, we try dividing 64,832,131 by 3:
64,832,131 ÷ 3 = 21,610,710.3333
If the quotient is a whole number, then 3 and 21,610,710.3333 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 | 64,832,131 | |
| -1 | -64,832,131 |
Let's try dividing by 4:
64,832,131 ÷ 4 = 16,208,032.75
If the quotient is a whole number, then 4 and 16,208,032.75 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 | 64,832,131 | |
| -1 | 64,832,131 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 491 | 1,451 | 3,437 | 6,383 | 10,157 | 18,863 | 44,681 | 132,041 | 712,441 | 4,987,087 | 9,261,733 | 64,832,131 |
| -1 | -7 | -13 | -91 | -491 | -1,451 | -3,437 | -6,383 | -10,157 | -18,863 | -44,681 | -132,041 | -712,441 | -4,987,087 | -9,261,733 | -64,832,131 |
