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 69,053,765, 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 | 69,053,765 | |
| -1 | -69,053,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,053,765.
Example:
1 x 69,053,765 = 69,053,765
and
-1 x -69,053,765 = 69,053,765
Notice both answers equal 69,053,765
With that explanation out of the way, let's continue. Next, we take the number 69,053,765 and divide it by 2:
69,053,765 ÷ 2 = 34,526,882.5
If the quotient is a whole number, then 2 and 34,526,882.5 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 | 69,053,765 | |
| -1 | -69,053,765 |
Now, we try dividing 69,053,765 by 3:
69,053,765 ÷ 3 = 23,017,921.6667
If the quotient is a whole number, then 3 and 23,017,921.6667 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 | 69,053,765 | |
| -1 | -69,053,765 |
Let's try dividing by 4:
69,053,765 ÷ 4 = 17,263,441.25
If the quotient is a whole number, then 4 and 17,263,441.25 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 | 69,053,765 | |
| -1 | 69,053,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 89 | 445 | 979 | 4,895 | 14,107 | 70,535 | 155,177 | 775,885 | 1,255,523 | 6,277,615 | 13,810,753 | 69,053,765 |
| -1 | -5 | -11 | -55 | -89 | -445 | -979 | -4,895 | -14,107 | -70,535 | -155,177 | -775,885 | -1,255,523 | -6,277,615 | -13,810,753 | -69,053,765 |
