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 177,552,613, 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 | 177,552,613 | |
| -1 | -177,552,613 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,552,613.
Example:
1 x 177,552,613 = 177,552,613
and
-1 x -177,552,613 = 177,552,613
Notice both answers equal 177,552,613
With that explanation out of the way, let's continue. Next, we take the number 177,552,613 and divide it by 2:
177,552,613 ÷ 2 = 88,776,306.5
If the quotient is a whole number, then 2 and 88,776,306.5 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 | 177,552,613 | |
| -1 | -177,552,613 |
Now, we try dividing 177,552,613 by 3:
177,552,613 ÷ 3 = 59,184,204.3333
If the quotient is a whole number, then 3 and 59,184,204.3333 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 | 177,552,613 | |
| -1 | -177,552,613 |
Let's try dividing by 4:
177,552,613 ÷ 4 = 44,388,153.25
If the quotient is a whole number, then 4 and 44,388,153.25 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 | 177,552,613 | |
| -1 | 177,552,613 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 347 | 469 | 1,091 | 2,429 | 7,637 | 23,249 | 73,097 | 162,743 | 378,577 | 511,679 | 2,650,039 | 25,364,659 | 177,552,613 |
| -1 | -7 | -67 | -347 | -469 | -1,091 | -2,429 | -7,637 | -23,249 | -73,097 | -162,743 | -378,577 | -511,679 | -2,650,039 | -25,364,659 | -177,552,613 |
