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 112,154,581, 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 | 112,154,581 | |
| -1 | -112,154,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,154,581.
Example:
1 x 112,154,581 = 112,154,581
and
-1 x -112,154,581 = 112,154,581
Notice both answers equal 112,154,581
With that explanation out of the way, let's continue. Next, we take the number 112,154,581 and divide it by 2:
112,154,581 ÷ 2 = 56,077,290.5
If the quotient is a whole number, then 2 and 56,077,290.5 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 | 112,154,581 | |
| -1 | -112,154,581 |
Now, we try dividing 112,154,581 by 3:
112,154,581 ÷ 3 = 37,384,860.3333
If the quotient is a whole number, then 3 and 37,384,860.3333 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 | 112,154,581 | |
| -1 | -112,154,581 |
Let's try dividing by 4:
112,154,581 ÷ 4 = 28,038,645.25
If the quotient is a whole number, then 4 and 28,038,645.25 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 | 112,154,581 | |
| -1 | 112,154,581 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 251 | 539 | 829 | 1,757 | 2,761 | 5,803 | 9,119 | 12,299 | 19,327 | 40,621 | 63,833 | 135,289 | 208,079 | 446,831 | 1,456,553 | 2,288,869 | 10,195,871 | 16,022,083 | 112,154,581 |
| -1 | -7 | -11 | -49 | -77 | -251 | -539 | -829 | -1,757 | -2,761 | -5,803 | -9,119 | -12,299 | -19,327 | -40,621 | -63,833 | -135,289 | -208,079 | -446,831 | -1,456,553 | -2,288,869 | -10,195,871 | -16,022,083 | -112,154,581 |
