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 177,164,525, 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 | 177,164,525 | |
| -1 | -177,164,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,164,525.
Example:
1 x 177,164,525 = 177,164,525
and
-1 x -177,164,525 = 177,164,525
Notice both answers equal 177,164,525
With that explanation out of the way, let's continue. Next, we take the number 177,164,525 and divide it by 2:
177,164,525 ÷ 2 = 88,582,262.5
If the quotient is a whole number, then 2 and 88,582,262.5 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 | 177,164,525 | |
| -1 | -177,164,525 |
Now, we try dividing 177,164,525 by 3:
177,164,525 ÷ 3 = 59,054,841.6667
If the quotient is a whole number, then 3 and 59,054,841.6667 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 | 177,164,525 | |
| -1 | -177,164,525 |
Let's try dividing by 4:
177,164,525 ÷ 4 = 44,291,131.25
If the quotient is a whole number, then 4 and 44,291,131.25 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 | 177,164,525 | |
| -1 | 177,164,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 151 | 355 | 661 | 755 | 1,775 | 3,305 | 3,775 | 10,721 | 16,525 | 46,931 | 53,605 | 99,811 | 234,655 | 268,025 | 499,055 | 1,173,275 | 2,495,275 | 7,086,581 | 35,432,905 | 177,164,525 |
| -1 | -5 | -25 | -71 | -151 | -355 | -661 | -755 | -1,775 | -3,305 | -3,775 | -10,721 | -16,525 | -46,931 | -53,605 | -99,811 | -234,655 | -268,025 | -499,055 | -1,173,275 | -2,495,275 | -7,086,581 | -35,432,905 | -177,164,525 |
