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 137,613,475, 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 | 137,613,475 | |
| -1 | -137,613,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,613,475.
Example:
1 x 137,613,475 = 137,613,475
and
-1 x -137,613,475 = 137,613,475
Notice both answers equal 137,613,475
With that explanation out of the way, let's continue. Next, we take the number 137,613,475 and divide it by 2:
137,613,475 ÷ 2 = 68,806,737.5
If the quotient is a whole number, then 2 and 68,806,737.5 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 | 137,613,475 | |
| -1 | -137,613,475 |
Now, we try dividing 137,613,475 by 3:
137,613,475 ÷ 3 = 45,871,158.3333
If the quotient is a whole number, then 3 and 45,871,158.3333 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 | 137,613,475 | |
| -1 | -137,613,475 |
Let's try dividing by 4:
137,613,475 ÷ 4 = 34,403,368.75
If the quotient is a whole number, then 4 and 34,403,368.75 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 | 137,613,475 | |
| -1 | 137,613,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 139 | 199 | 695 | 995 | 3,475 | 4,975 | 27,661 | 39,601 | 138,305 | 198,005 | 691,525 | 990,025 | 5,504,539 | 27,522,695 | 137,613,475 |
| -1 | -5 | -25 | -139 | -199 | -695 | -995 | -3,475 | -4,975 | -27,661 | -39,601 | -138,305 | -198,005 | -691,525 | -990,025 | -5,504,539 | -27,522,695 | -137,613,475 |
