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 177,455,341, 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 | 177,455,341 | |
| -1 | -177,455,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,455,341.
Example:
1 x 177,455,341 = 177,455,341
and
-1 x -177,455,341 = 177,455,341
Notice both answers equal 177,455,341
With that explanation out of the way, let's continue. Next, we take the number 177,455,341 and divide it by 2:
177,455,341 ÷ 2 = 88,727,670.5
If the quotient is a whole number, then 2 and 88,727,670.5 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 | 177,455,341 | |
| -1 | -177,455,341 |
Now, we try dividing 177,455,341 by 3:
177,455,341 ÷ 3 = 59,151,780.3333
If the quotient is a whole number, then 3 and 59,151,780.3333 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 | 177,455,341 | |
| -1 | -177,455,341 |
Let's try dividing by 4:
177,455,341 ÷ 4 = 44,363,835.25
If the quotient is a whole number, then 4 and 44,363,835.25 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 | 177,455,341 | |
| -1 | 177,455,341 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 277 | 497 | 1,289 | 1,939 | 9,023 | 19,667 | 91,519 | 137,669 | 357,053 | 640,633 | 2,499,371 | 25,350,763 | 177,455,341 |
| -1 | -7 | -71 | -277 | -497 | -1,289 | -1,939 | -9,023 | -19,667 | -91,519 | -137,669 | -357,053 | -640,633 | -2,499,371 | -25,350,763 | -177,455,341 |
