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 69,229,655, 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 | 69,229,655 | |
| -1 | -69,229,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,229,655.
Example:
1 x 69,229,655 = 69,229,655
and
-1 x -69,229,655 = 69,229,655
Notice both answers equal 69,229,655
With that explanation out of the way, let's continue. Next, we take the number 69,229,655 and divide it by 2:
69,229,655 ÷ 2 = 34,614,827.5
If the quotient is a whole number, then 2 and 34,614,827.5 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 | 69,229,655 | |
| -1 | -69,229,655 |
Now, we try dividing 69,229,655 by 3:
69,229,655 ÷ 3 = 23,076,551.6667
If the quotient is a whole number, then 3 and 23,076,551.6667 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 | 69,229,655 | |
| -1 | -69,229,655 |
Let's try dividing by 4:
69,229,655 ÷ 4 = 17,307,413.75
If the quotient is a whole number, then 4 and 17,307,413.75 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 | 69,229,655 | |
| -1 | 69,229,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 54,727 | 273,635 | 601,997 | 1,258,721 | 3,009,985 | 6,293,605 | 13,845,931 | 69,229,655 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -54,727 | -273,635 | -601,997 | -1,258,721 | -3,009,985 | -6,293,605 | -13,845,931 | -69,229,655 |
