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 137,713,075, 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 | 137,713,075 | |
| -1 | -137,713,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,713,075.
Example:
1 x 137,713,075 = 137,713,075
and
-1 x -137,713,075 = 137,713,075
Notice both answers equal 137,713,075
With that explanation out of the way, let's continue. Next, we take the number 137,713,075 and divide it by 2:
137,713,075 ÷ 2 = 68,856,537.5
If the quotient is a whole number, then 2 and 68,856,537.5 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 | 137,713,075 | |
| -1 | -137,713,075 |
Now, we try dividing 137,713,075 by 3:
137,713,075 ÷ 3 = 45,904,358.3333
If the quotient is a whole number, then 3 and 45,904,358.3333 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 | 137,713,075 | |
| -1 | -137,713,075 |
Let's try dividing by 4:
137,713,075 ÷ 4 = 34,428,268.75
If the quotient is a whole number, then 4 and 34,428,268.75 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 | 137,713,075 | |
| -1 | 137,713,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 37 | 115 | 185 | 575 | 851 | 925 | 4,255 | 6,473 | 21,275 | 32,365 | 148,879 | 161,825 | 239,501 | 744,395 | 1,197,505 | 3,721,975 | 5,508,523 | 5,987,525 | 27,542,615 | 137,713,075 |
| -1 | -5 | -23 | -25 | -37 | -115 | -185 | -575 | -851 | -925 | -4,255 | -6,473 | -21,275 | -32,365 | -148,879 | -161,825 | -239,501 | -744,395 | -1,197,505 | -3,721,975 | -5,508,523 | -5,987,525 | -27,542,615 | -137,713,075 |
