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 65,326,157, 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 | 65,326,157 | |
| -1 | -65,326,157 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,326,157.
Example:
1 x 65,326,157 = 65,326,157
and
-1 x -65,326,157 = 65,326,157
Notice both answers equal 65,326,157
With that explanation out of the way, let's continue. Next, we take the number 65,326,157 and divide it by 2:
65,326,157 ÷ 2 = 32,663,078.5
If the quotient is a whole number, then 2 and 32,663,078.5 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 | 65,326,157 | |
| -1 | -65,326,157 |
Now, we try dividing 65,326,157 by 3:
65,326,157 ÷ 3 = 21,775,385.6667
If the quotient is a whole number, then 3 and 21,775,385.6667 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 | 65,326,157 | |
| -1 | -65,326,157 |
Let's try dividing by 4:
65,326,157 ÷ 4 = 16,331,539.25
If the quotient is a whole number, then 4 and 16,331,539.25 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 | 65,326,157 | |
| -1 | 65,326,157 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 59 | 689 | 767 | 1,607 | 3,127 | 20,891 | 40,651 | 85,171 | 94,813 | 1,107,223 | 1,232,569 | 5,025,089 | 65,326,157 |
| -1 | -13 | -53 | -59 | -689 | -767 | -1,607 | -3,127 | -20,891 | -40,651 | -85,171 | -94,813 | -1,107,223 | -1,232,569 | -5,025,089 | -65,326,157 |
