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 69,163,115, 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 | 69,163,115 | |
| -1 | -69,163,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,163,115.
Example:
1 x 69,163,115 = 69,163,115
and
-1 x -69,163,115 = 69,163,115
Notice both answers equal 69,163,115
With that explanation out of the way, let's continue. Next, we take the number 69,163,115 and divide it by 2:
69,163,115 ÷ 2 = 34,581,557.5
If the quotient is a whole number, then 2 and 34,581,557.5 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 | 69,163,115 | |
| -1 | -69,163,115 |
Now, we try dividing 69,163,115 by 3:
69,163,115 ÷ 3 = 23,054,371.6667
If the quotient is a whole number, then 3 and 23,054,371.6667 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 | 69,163,115 | |
| -1 | -69,163,115 |
Let's try dividing by 4:
69,163,115 ÷ 4 = 17,290,778.75
If the quotient is a whole number, then 4 and 17,290,778.75 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 | 69,163,115 | |
| -1 | 69,163,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 68,141 | 340,705 | 476,987 | 1,976,089 | 2,384,935 | 9,880,445 | 13,832,623 | 69,163,115 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -68,141 | -340,705 | -476,987 | -1,976,089 | -2,384,935 | -9,880,445 | -13,832,623 | -69,163,115 |
