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 160,166,053, 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 | 160,166,053 | |
| -1 | -160,166,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,166,053.
Example:
1 x 160,166,053 = 160,166,053
and
-1 x -160,166,053 = 160,166,053
Notice both answers equal 160,166,053
With that explanation out of the way, let's continue. Next, we take the number 160,166,053 and divide it by 2:
160,166,053 ÷ 2 = 80,083,026.5
If the quotient is a whole number, then 2 and 80,083,026.5 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 | 160,166,053 | |
| -1 | -160,166,053 |
Now, we try dividing 160,166,053 by 3:
160,166,053 ÷ 3 = 53,388,684.3333
If the quotient is a whole number, then 3 and 53,388,684.3333 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 | 160,166,053 | |
| -1 | -160,166,053 |
Let's try dividing by 4:
160,166,053 ÷ 4 = 40,041,513.25
If the quotient is a whole number, then 4 and 40,041,513.25 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 | 160,166,053 | |
| -1 | 160,166,053 |
If you did it right, you will end up with this table:
| 1 | 53 | 61 | 107 | 463 | 3,233 | 5,671 | 6,527 | 24,539 | 28,243 | 49,541 | 345,931 | 1,496,879 | 2,625,673 | 3,022,001 | 160,166,053 |
| -1 | -53 | -61 | -107 | -463 | -3,233 | -5,671 | -6,527 | -24,539 | -28,243 | -49,541 | -345,931 | -1,496,879 | -2,625,673 | -3,022,001 | -160,166,053 |
