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 112,121,065, 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 | 112,121,065 | |
| -1 | -112,121,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,121,065.
Example:
1 x 112,121,065 = 112,121,065
and
-1 x -112,121,065 = 112,121,065
Notice both answers equal 112,121,065
With that explanation out of the way, let's continue. Next, we take the number 112,121,065 and divide it by 2:
112,121,065 ÷ 2 = 56,060,532.5
If the quotient is a whole number, then 2 and 56,060,532.5 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 | 112,121,065 | |
| -1 | -112,121,065 |
Now, we try dividing 112,121,065 by 3:
112,121,065 ÷ 3 = 37,373,688.3333
If the quotient is a whole number, then 3 and 37,373,688.3333 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 | 112,121,065 | |
| -1 | -112,121,065 |
Let's try dividing by 4:
112,121,065 ÷ 4 = 28,030,266.25
If the quotient is a whole number, then 4 and 28,030,266.25 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 | 112,121,065 | |
| -1 | 112,121,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 73 | 245 | 365 | 511 | 2,555 | 3,577 | 6,269 | 17,885 | 31,345 | 43,883 | 219,415 | 307,181 | 457,637 | 1,535,905 | 2,288,185 | 3,203,459 | 16,017,295 | 22,424,213 | 112,121,065 |
| -1 | -5 | -7 | -35 | -49 | -73 | -245 | -365 | -511 | -2,555 | -3,577 | -6,269 | -17,885 | -31,345 | -43,883 | -219,415 | -307,181 | -457,637 | -1,535,905 | -2,288,185 | -3,203,459 | -16,017,295 | -22,424,213 | -112,121,065 |
