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 69,376,391, 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 | 69,376,391 | |
| -1 | -69,376,391 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,376,391.
Example:
1 x 69,376,391 = 69,376,391
and
-1 x -69,376,391 = 69,376,391
Notice both answers equal 69,376,391
With that explanation out of the way, let's continue. Next, we take the number 69,376,391 and divide it by 2:
69,376,391 ÷ 2 = 34,688,195.5
If the quotient is a whole number, then 2 and 34,688,195.5 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 | 69,376,391 | |
| -1 | -69,376,391 |
Now, we try dividing 69,376,391 by 3:
69,376,391 ÷ 3 = 23,125,463.6667
If the quotient is a whole number, then 3 and 23,125,463.6667 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 | 69,376,391 | |
| -1 | -69,376,391 |
Let's try dividing by 4:
69,376,391 ÷ 4 = 17,344,097.75
If the quotient is a whole number, then 4 and 17,344,097.75 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 | 69,376,391 | |
| -1 | 69,376,391 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 359 | 1,453 | 2,513 | 6,821 | 10,171 | 27,607 | 47,747 | 193,249 | 521,627 | 3,651,389 | 9,910,913 | 69,376,391 |
| -1 | -7 | -19 | -133 | -359 | -1,453 | -2,513 | -6,821 | -10,171 | -27,607 | -47,747 | -193,249 | -521,627 | -3,651,389 | -9,910,913 | -69,376,391 |
