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 170,011,555, 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 | 170,011,555 | |
| -1 | -170,011,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 170,011,555.
Example:
1 x 170,011,555 = 170,011,555
and
-1 x -170,011,555 = 170,011,555
Notice both answers equal 170,011,555
With that explanation out of the way, let's continue. Next, we take the number 170,011,555 and divide it by 2:
170,011,555 ÷ 2 = 85,005,777.5
If the quotient is a whole number, then 2 and 85,005,777.5 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 | 170,011,555 | |
| -1 | -170,011,555 |
Now, we try dividing 170,011,555 by 3:
170,011,555 ÷ 3 = 56,670,518.3333
If the quotient is a whole number, then 3 and 56,670,518.3333 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 | 170,011,555 | |
| -1 | -170,011,555 |
Let's try dividing by 4:
170,011,555 ÷ 4 = 42,502,888.75
If the quotient is a whole number, then 4 and 42,502,888.75 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 | 170,011,555 | |
| -1 | 170,011,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 61,487 | 307,435 | 430,409 | 2,152,045 | 4,857,473 | 24,287,365 | 34,002,311 | 170,011,555 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -61,487 | -307,435 | -430,409 | -2,152,045 | -4,857,473 | -24,287,365 | -34,002,311 | -170,011,555 |
