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 65,923,637, 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 | 65,923,637 | |
| -1 | -65,923,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,923,637.
Example:
1 x 65,923,637 = 65,923,637
and
-1 x -65,923,637 = 65,923,637
Notice both answers equal 65,923,637
With that explanation out of the way, let's continue. Next, we take the number 65,923,637 and divide it by 2:
65,923,637 ÷ 2 = 32,961,818.5
If the quotient is a whole number, then 2 and 32,961,818.5 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 | 65,923,637 | |
| -1 | -65,923,637 |
Now, we try dividing 65,923,637 by 3:
65,923,637 ÷ 3 = 21,974,545.6667
If the quotient is a whole number, then 3 and 21,974,545.6667 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 | 65,923,637 | |
| -1 | -65,923,637 |
Let's try dividing by 4:
65,923,637 ÷ 4 = 16,480,909.25
If the quotient is a whole number, then 4 and 16,480,909.25 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 | 65,923,637 | |
| -1 | 65,923,637 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 317 | 941 | 4,121 | 5,389 | 12,233 | 15,997 | 70,057 | 207,961 | 298,297 | 3,877,861 | 5,071,049 | 65,923,637 |
| -1 | -13 | -17 | -221 | -317 | -941 | -4,121 | -5,389 | -12,233 | -15,997 | -70,057 | -207,961 | -298,297 | -3,877,861 | -5,071,049 | -65,923,637 |
