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 165,237,425, 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 | 165,237,425 | |
| -1 | -165,237,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 165,237,425.
Example:
1 x 165,237,425 = 165,237,425
and
-1 x -165,237,425 = 165,237,425
Notice both answers equal 165,237,425
With that explanation out of the way, let's continue. Next, we take the number 165,237,425 and divide it by 2:
165,237,425 ÷ 2 = 82,618,712.5
If the quotient is a whole number, then 2 and 82,618,712.5 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 | 165,237,425 | |
| -1 | -165,237,425 |
Now, we try dividing 165,237,425 by 3:
165,237,425 ÷ 3 = 55,079,141.6667
If the quotient is a whole number, then 3 and 55,079,141.6667 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 | 165,237,425 | |
| -1 | -165,237,425 |
Let's try dividing by 4:
165,237,425 ÷ 4 = 41,309,356.25
If the quotient is a whole number, then 4 and 41,309,356.25 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 | 165,237,425 | |
| -1 | 165,237,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 107 | 223 | 277 | 535 | 1,115 | 1,385 | 2,675 | 5,575 | 6,925 | 23,861 | 29,639 | 61,771 | 119,305 | 148,195 | 308,855 | 596,525 | 740,975 | 1,544,275 | 6,609,497 | 33,047,485 | 165,237,425 |
| -1 | -5 | -25 | -107 | -223 | -277 | -535 | -1,115 | -1,385 | -2,675 | -5,575 | -6,925 | -23,861 | -29,639 | -61,771 | -119,305 | -148,195 | -308,855 | -596,525 | -740,975 | -1,544,275 | -6,609,497 | -33,047,485 | -165,237,425 |
