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 115,745,363, 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 | 115,745,363 | |
-1 | -115,745,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,745,363.
Example:
1 x 115,745,363 = 115,745,363
and
-1 x -115,745,363 = 115,745,363
Notice both answers equal 115,745,363
With that explanation out of the way, let's continue. Next, we take the number 115,745,363 and divide it by 2:
115,745,363 ÷ 2 = 57,872,681.5
If the quotient is a whole number, then 2 and 57,872,681.5 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 | 115,745,363 | |
-1 | -115,745,363 |
Now, we try dividing 115,745,363 by 3:
115,745,363 ÷ 3 = 38,581,787.6667
If the quotient is a whole number, then 3 and 38,581,787.6667 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 | 115,745,363 | |
-1 | -115,745,363 |
Let's try dividing by 4:
115,745,363 ÷ 4 = 28,936,340.75
If the quotient is a whole number, then 4 and 28,936,340.75 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 | 115,745,363 | |
-1 | 115,745,363 |
If you did it right, you will end up with this table:
1 | 4,931 | 23,473 | 115,745,363 |
-1 | -4,931 | -23,473 | -115,745,363 |
