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 176,157,541, 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 | 176,157,541 | |
| -1 | -176,157,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,157,541.
Example:
1 x 176,157,541 = 176,157,541
and
-1 x -176,157,541 = 176,157,541
Notice both answers equal 176,157,541
With that explanation out of the way, let's continue. Next, we take the number 176,157,541 and divide it by 2:
176,157,541 ÷ 2 = 88,078,770.5
If the quotient is a whole number, then 2 and 88,078,770.5 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 | 176,157,541 | |
| -1 | -176,157,541 |
Now, we try dividing 176,157,541 by 3:
176,157,541 ÷ 3 = 58,719,180.3333
If the quotient is a whole number, then 3 and 58,719,180.3333 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 | 176,157,541 | |
| -1 | -176,157,541 |
Let's try dividing by 4:
176,157,541 ÷ 4 = 44,039,385.25
If the quotient is a whole number, then 4 and 44,039,385.25 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 | 176,157,541 | |
| -1 | 176,157,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 73 | 301 | 511 | 3,139 | 8,017 | 21,973 | 56,119 | 344,731 | 585,241 | 2,413,117 | 4,096,687 | 25,165,363 | 176,157,541 |
| -1 | -7 | -43 | -73 | -301 | -511 | -3,139 | -8,017 | -21,973 | -56,119 | -344,731 | -585,241 | -2,413,117 | -4,096,687 | -25,165,363 | -176,157,541 |
