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 177,423,701, 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 | 177,423,701 | |
| -1 | -177,423,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,423,701.
Example:
1 x 177,423,701 = 177,423,701
and
-1 x -177,423,701 = 177,423,701
Notice both answers equal 177,423,701
With that explanation out of the way, let's continue. Next, we take the number 177,423,701 and divide it by 2:
177,423,701 ÷ 2 = 88,711,850.5
If the quotient is a whole number, then 2 and 88,711,850.5 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 | 177,423,701 | |
| -1 | -177,423,701 |
Now, we try dividing 177,423,701 by 3:
177,423,701 ÷ 3 = 59,141,233.6667
If the quotient is a whole number, then 3 and 59,141,233.6667 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 | 177,423,701 | |
| -1 | -177,423,701 |
Let's try dividing by 4:
177,423,701 ÷ 4 = 44,355,925.25
If the quotient is a whole number, then 4 and 44,355,925.25 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 | 177,423,701 | |
| -1 | 177,423,701 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 53 | 91 | 371 | 689 | 4,823 | 36,787 | 257,509 | 478,231 | 1,949,711 | 3,347,617 | 13,647,977 | 25,346,243 | 177,423,701 |
| -1 | -7 | -13 | -53 | -91 | -371 | -689 | -4,823 | -36,787 | -257,509 | -478,231 | -1,949,711 | -3,347,617 | -13,647,977 | -25,346,243 | -177,423,701 |
