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 65,743,657, 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 | 65,743,657 | |
| -1 | -65,743,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,743,657.
Example:
1 x 65,743,657 = 65,743,657
and
-1 x -65,743,657 = 65,743,657
Notice both answers equal 65,743,657
With that explanation out of the way, let's continue. Next, we take the number 65,743,657 and divide it by 2:
65,743,657 ÷ 2 = 32,871,828.5
If the quotient is a whole number, then 2 and 32,871,828.5 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 | 65,743,657 | |
| -1 | -65,743,657 |
Now, we try dividing 65,743,657 by 3:
65,743,657 ÷ 3 = 21,914,552.3333
If the quotient is a whole number, then 3 and 21,914,552.3333 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 | 65,743,657 | |
| -1 | -65,743,657 |
Let's try dividing by 4:
65,743,657 ÷ 4 = 16,435,914.25
If the quotient is a whole number, then 4 and 16,435,914.25 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 | 65,743,657 | |
| -1 | 65,743,657 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 179 | 497 | 739 | 1,253 | 5,173 | 12,709 | 52,469 | 88,963 | 132,281 | 367,283 | 925,967 | 9,391,951 | 65,743,657 |
| -1 | -7 | -71 | -179 | -497 | -739 | -1,253 | -5,173 | -12,709 | -52,469 | -88,963 | -132,281 | -367,283 | -925,967 | -9,391,951 | -65,743,657 |
