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 167,420,227, 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 | 167,420,227 | |
| -1 | -167,420,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,420,227.
Example:
1 x 167,420,227 = 167,420,227
and
-1 x -167,420,227 = 167,420,227
Notice both answers equal 167,420,227
With that explanation out of the way, let's continue. Next, we take the number 167,420,227 and divide it by 2:
167,420,227 ÷ 2 = 83,710,113.5
If the quotient is a whole number, then 2 and 83,710,113.5 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 | 167,420,227 | |
| -1 | -167,420,227 |
Now, we try dividing 167,420,227 by 3:
167,420,227 ÷ 3 = 55,806,742.3333
If the quotient is a whole number, then 3 and 55,806,742.3333 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 | 167,420,227 | |
| -1 | -167,420,227 |
Let's try dividing by 4:
167,420,227 ÷ 4 = 41,855,056.75
If the quotient is a whole number, then 4 and 41,855,056.75 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 | 167,420,227 | |
| -1 | 167,420,227 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 131 | 481 | 1,703 | 2,657 | 4,847 | 34,541 | 63,011 | 98,309 | 348,067 | 1,278,017 | 4,524,871 | 12,878,479 | 167,420,227 |
| -1 | -13 | -37 | -131 | -481 | -1,703 | -2,657 | -4,847 | -34,541 | -63,011 | -98,309 | -348,067 | -1,278,017 | -4,524,871 | -12,878,479 | -167,420,227 |
