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 137,704,565, 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 | 137,704,565 | |
| -1 | -137,704,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,704,565.
Example:
1 x 137,704,565 = 137,704,565
and
-1 x -137,704,565 = 137,704,565
Notice both answers equal 137,704,565
With that explanation out of the way, let's continue. Next, we take the number 137,704,565 and divide it by 2:
137,704,565 ÷ 2 = 68,852,282.5
If the quotient is a whole number, then 2 and 68,852,282.5 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 | 137,704,565 | |
| -1 | -137,704,565 |
Now, we try dividing 137,704,565 by 3:
137,704,565 ÷ 3 = 45,901,521.6667
If the quotient is a whole number, then 3 and 45,901,521.6667 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 | 137,704,565 | |
| -1 | -137,704,565 |
Let's try dividing by 4:
137,704,565 ÷ 4 = 34,426,141.25
If the quotient is a whole number, then 4 and 34,426,141.25 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 | 137,704,565 | |
| -1 | 137,704,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 32,363 | 161,815 | 744,349 | 1,197,431 | 3,721,745 | 5,987,155 | 27,540,913 | 137,704,565 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -32,363 | -161,815 | -744,349 | -1,197,431 | -3,721,745 | -5,987,155 | -27,540,913 | -137,704,565 |
