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 177,444,547, 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 | 177,444,547 | |
| -1 | -177,444,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,444,547.
Example:
1 x 177,444,547 = 177,444,547
and
-1 x -177,444,547 = 177,444,547
Notice both answers equal 177,444,547
With that explanation out of the way, let's continue. Next, we take the number 177,444,547 and divide it by 2:
177,444,547 ÷ 2 = 88,722,273.5
If the quotient is a whole number, then 2 and 88,722,273.5 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 | 177,444,547 | |
| -1 | -177,444,547 |
Now, we try dividing 177,444,547 by 3:
177,444,547 ÷ 3 = 59,148,182.3333
If the quotient is a whole number, then 3 and 59,148,182.3333 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 | 177,444,547 | |
| -1 | -177,444,547 |
Let's try dividing by 4:
177,444,547 ÷ 4 = 44,361,136.75
If the quotient is a whole number, then 4 and 44,361,136.75 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 | 177,444,547 | |
| -1 | 177,444,547 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 149 | 427 | 1,043 | 2,789 | 9,089 | 19,523 | 63,623 | 170,129 | 415,561 | 1,190,903 | 2,908,927 | 25,349,221 | 177,444,547 |
| -1 | -7 | -61 | -149 | -427 | -1,043 | -2,789 | -9,089 | -19,523 | -63,623 | -170,129 | -415,561 | -1,190,903 | -2,908,927 | -25,349,221 | -177,444,547 |
