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 167,065,045, 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 | 167,065,045 | |
| -1 | -167,065,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,065,045.
Example:
1 x 167,065,045 = 167,065,045
and
-1 x -167,065,045 = 167,065,045
Notice both answers equal 167,065,045
With that explanation out of the way, let's continue. Next, we take the number 167,065,045 and divide it by 2:
167,065,045 ÷ 2 = 83,532,522.5
If the quotient is a whole number, then 2 and 83,532,522.5 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 | 167,065,045 | |
| -1 | -167,065,045 |
Now, we try dividing 167,065,045 by 3:
167,065,045 ÷ 3 = 55,688,348.3333
If the quotient is a whole number, then 3 and 55,688,348.3333 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 | 167,065,045 | |
| -1 | -167,065,045 |
Let's try dividing by 4:
167,065,045 ÷ 4 = 41,766,261.25
If the quotient is a whole number, then 4 and 41,766,261.25 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 | 167,065,045 | |
| -1 | 167,065,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 961 | 1,085 | 4,805 | 4,967 | 6,727 | 24,835 | 33,635 | 34,769 | 153,977 | 173,845 | 769,885 | 1,077,839 | 4,773,287 | 5,389,195 | 23,866,435 | 33,413,009 | 167,065,045 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -961 | -1,085 | -4,805 | -4,967 | -6,727 | -24,835 | -33,635 | -34,769 | -153,977 | -173,845 | -769,885 | -1,077,839 | -4,773,287 | -5,389,195 | -23,866,435 | -33,413,009 | -167,065,045 |
