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 73,161,077, 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 | 73,161,077 | |
| -1 | -73,161,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 73,161,077.
Example:
1 x 73,161,077 = 73,161,077
and
-1 x -73,161,077 = 73,161,077
Notice both answers equal 73,161,077
With that explanation out of the way, let's continue. Next, we take the number 73,161,077 and divide it by 2:
73,161,077 ÷ 2 = 36,580,538.5
If the quotient is a whole number, then 2 and 36,580,538.5 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 | 73,161,077 | |
| -1 | -73,161,077 |
Now, we try dividing 73,161,077 by 3:
73,161,077 ÷ 3 = 24,387,025.6667
If the quotient is a whole number, then 3 and 24,387,025.6667 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 | 73,161,077 | |
| -1 | -73,161,077 |
Let's try dividing by 4:
73,161,077 ÷ 4 = 18,290,269.25
If the quotient is a whole number, then 4 and 18,290,269.25 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 | 73,161,077 | |
| -1 | 73,161,077 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 121 | 209 | 263 | 1,331 | 2,299 | 2,893 | 4,997 | 14,641 | 25,289 | 31,823 | 54,967 | 278,179 | 350,053 | 604,637 | 3,850,583 | 6,651,007 | 73,161,077 |
| -1 | -11 | -19 | -121 | -209 | -263 | -1,331 | -2,299 | -2,893 | -4,997 | -14,641 | -25,289 | -31,823 | -54,967 | -278,179 | -350,053 | -604,637 | -3,850,583 | -6,651,007 | -73,161,077 |
