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 101,242,297, 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 | 101,242,297 | |
| -1 | -101,242,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,242,297.
Example:
1 x 101,242,297 = 101,242,297
and
-1 x -101,242,297 = 101,242,297
Notice both answers equal 101,242,297
With that explanation out of the way, let's continue. Next, we take the number 101,242,297 and divide it by 2:
101,242,297 ÷ 2 = 50,621,148.5
If the quotient is a whole number, then 2 and 50,621,148.5 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 | 101,242,297 | |
| -1 | -101,242,297 |
Now, we try dividing 101,242,297 by 3:
101,242,297 ÷ 3 = 33,747,432.3333
If the quotient is a whole number, then 3 and 33,747,432.3333 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 | 101,242,297 | |
| -1 | -101,242,297 |
Let's try dividing by 4:
101,242,297 ÷ 4 = 25,310,574.25
If the quotient is a whole number, then 4 and 25,310,574.25 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 | 101,242,297 | |
| -1 | 101,242,297 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 571 | 593 | 7,423 | 7,709 | 13,133 | 13,639 | 170,729 | 177,307 | 338,603 | 4,401,839 | 7,787,869 | 101,242,297 |
| -1 | -13 | -23 | -299 | -571 | -593 | -7,423 | -7,709 | -13,133 | -13,639 | -170,729 | -177,307 | -338,603 | -4,401,839 | -7,787,869 | -101,242,297 |
