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 167,374,265, 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 | 167,374,265 | |
| -1 | -167,374,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 167,374,265.
Example:
1 x 167,374,265 = 167,374,265
and
-1 x -167,374,265 = 167,374,265
Notice both answers equal 167,374,265
With that explanation out of the way, let's continue. Next, we take the number 167,374,265 and divide it by 2:
167,374,265 ÷ 2 = 83,687,132.5
If the quotient is a whole number, then 2 and 83,687,132.5 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 | 167,374,265 | |
| -1 | -167,374,265 |
Now, we try dividing 167,374,265 by 3:
167,374,265 ÷ 3 = 55,791,421.6667
If the quotient is a whole number, then 3 and 55,791,421.6667 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 | 167,374,265 | |
| -1 | -167,374,265 |
Let's try dividing by 4:
167,374,265 ÷ 4 = 41,843,566.25
If the quotient is a whole number, then 4 and 41,843,566.25 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 | 167,374,265 | |
| -1 | 167,374,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 701 | 901 | 2,809 | 3,505 | 4,505 | 11,917 | 14,045 | 37,153 | 47,753 | 59,585 | 185,765 | 238,765 | 631,601 | 1,969,109 | 3,158,005 | 9,845,545 | 33,474,853 | 167,374,265 |
| -1 | -5 | -17 | -53 | -85 | -265 | -701 | -901 | -2,809 | -3,505 | -4,505 | -11,917 | -14,045 | -37,153 | -47,753 | -59,585 | -185,765 | -238,765 | -631,601 | -1,969,109 | -3,158,005 | -9,845,545 | -33,474,853 | -167,374,265 |
