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 69,000,127, 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 | 69,000,127 | |
| -1 | -69,000,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,000,127.
Example:
1 x 69,000,127 = 69,000,127
and
-1 x -69,000,127 = 69,000,127
Notice both answers equal 69,000,127
With that explanation out of the way, let's continue. Next, we take the number 69,000,127 and divide it by 2:
69,000,127 ÷ 2 = 34,500,063.5
If the quotient is a whole number, then 2 and 34,500,063.5 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 | 69,000,127 | |
| -1 | -69,000,127 |
Now, we try dividing 69,000,127 by 3:
69,000,127 ÷ 3 = 23,000,042.3333
If the quotient is a whole number, then 3 and 23,000,042.3333 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 | 69,000,127 | |
| -1 | -69,000,127 |
Let's try dividing by 4:
69,000,127 ÷ 4 = 17,250,031.75
If the quotient is a whole number, then 4 and 17,250,031.75 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 | 69,000,127 | |
| -1 | 69,000,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 107 | 119 | 749 | 1,819 | 5,419 | 12,733 | 37,933 | 92,123 | 579,833 | 644,861 | 4,058,831 | 9,857,161 | 69,000,127 |
| -1 | -7 | -17 | -107 | -119 | -749 | -1,819 | -5,419 | -12,733 | -37,933 | -92,123 | -579,833 | -644,861 | -4,058,831 | -9,857,161 | -69,000,127 |
