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 365,305,157, 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 | 365,305,157 | |
| -1 | -365,305,157 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 365,305,157.
Example:
1 x 365,305,157 = 365,305,157
and
-1 x -365,305,157 = 365,305,157
Notice both answers equal 365,305,157
With that explanation out of the way, let's continue. Next, we take the number 365,305,157 and divide it by 2:
365,305,157 ÷ 2 = 182,652,578.5
If the quotient is a whole number, then 2 and 182,652,578.5 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 | 365,305,157 | |
| -1 | -365,305,157 |
Now, we try dividing 365,305,157 by 3:
365,305,157 ÷ 3 = 121,768,385.6667
If the quotient is a whole number, then 3 and 121,768,385.6667 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 | 365,305,157 | |
| -1 | -365,305,157 |
Let's try dividing by 4:
365,305,157 ÷ 4 = 91,326,289.25
If the quotient is a whole number, then 4 and 91,326,289.25 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 | 365,305,157 | |
| -1 | 365,305,157 |
If you did it right, you will end up with this table:
| 1 | 7 | 113 | 137 | 791 | 959 | 3,371 | 15,481 | 23,597 | 108,367 | 380,923 | 461,827 | 2,666,461 | 3,232,789 | 52,186,451 | 365,305,157 |
| -1 | -7 | -113 | -137 | -791 | -959 | -3,371 | -15,481 | -23,597 | -108,367 | -380,923 | -461,827 | -2,666,461 | -3,232,789 | -52,186,451 | -365,305,157 |
