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 136,272,745, 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 | 136,272,745 | |
| -1 | -136,272,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,272,745.
Example:
1 x 136,272,745 = 136,272,745
and
-1 x -136,272,745 = 136,272,745
Notice both answers equal 136,272,745
With that explanation out of the way, let's continue. Next, we take the number 136,272,745 and divide it by 2:
136,272,745 ÷ 2 = 68,136,372.5
If the quotient is a whole number, then 2 and 68,136,372.5 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 | 136,272,745 | |
| -1 | -136,272,745 |
Now, we try dividing 136,272,745 by 3:
136,272,745 ÷ 3 = 45,424,248.3333
If the quotient is a whole number, then 3 and 45,424,248.3333 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 | 136,272,745 | |
| -1 | -136,272,745 |
Let's try dividing by 4:
136,272,745 ÷ 4 = 34,068,186.25
If the quotient is a whole number, then 4 and 34,068,186.25 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 | 136,272,745 | |
| -1 | 136,272,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 125,597 | 627,985 | 879,179 | 3,893,507 | 4,395,895 | 19,467,535 | 27,254,549 | 136,272,745 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -125,597 | -627,985 | -879,179 | -3,893,507 | -4,395,895 | -19,467,535 | -27,254,549 | -136,272,745 |
