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 136,253,453, 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 | 136,253,453 | |
| -1 | -136,253,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,253,453.
Example:
1 x 136,253,453 = 136,253,453
and
-1 x -136,253,453 = 136,253,453
Notice both answers equal 136,253,453
With that explanation out of the way, let's continue. Next, we take the number 136,253,453 and divide it by 2:
136,253,453 ÷ 2 = 68,126,726.5
If the quotient is a whole number, then 2 and 68,126,726.5 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 | 136,253,453 | |
| -1 | -136,253,453 |
Now, we try dividing 136,253,453 by 3:
136,253,453 ÷ 3 = 45,417,817.6667
If the quotient is a whole number, then 3 and 45,417,817.6667 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 | 136,253,453 | |
| -1 | -136,253,453 |
Let's try dividing by 4:
136,253,453 ÷ 4 = 34,063,363.25
If the quotient is a whole number, then 4 and 34,063,363.25 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 | 136,253,453 | |
| -1 | 136,253,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 691 | 1,657 | 4,837 | 11,599 | 11,747 | 28,169 | 82,229 | 197,183 | 1,144,987 | 8,014,909 | 19,464,779 | 136,253,453 |
| -1 | -7 | -17 | -119 | -691 | -1,657 | -4,837 | -11,599 | -11,747 | -28,169 | -82,229 | -197,183 | -1,144,987 | -8,014,909 | -19,464,779 | -136,253,453 |
