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 112,443,541, 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 | 112,443,541 | |
| -1 | -112,443,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,443,541.
Example:
1 x 112,443,541 = 112,443,541
and
-1 x -112,443,541 = 112,443,541
Notice both answers equal 112,443,541
With that explanation out of the way, let's continue. Next, we take the number 112,443,541 and divide it by 2:
112,443,541 ÷ 2 = 56,221,770.5
If the quotient is a whole number, then 2 and 56,221,770.5 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 | 112,443,541 | |
| -1 | -112,443,541 |
Now, we try dividing 112,443,541 by 3:
112,443,541 ÷ 3 = 37,481,180.3333
If the quotient is a whole number, then 3 and 37,481,180.3333 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 | 112,443,541 | |
| -1 | -112,443,541 |
Let's try dividing by 4:
112,443,541 ÷ 4 = 28,110,885.25
If the quotient is a whole number, then 4 and 28,110,885.25 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 | 112,443,541 | |
| -1 | 112,443,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 283 | 1,831 | 1,981 | 8,773 | 12,817 | 56,761 | 61,411 | 397,327 | 518,173 | 3,627,211 | 16,063,363 | 112,443,541 |
| -1 | -7 | -31 | -217 | -283 | -1,831 | -1,981 | -8,773 | -12,817 | -56,761 | -61,411 | -397,327 | -518,173 | -3,627,211 | -16,063,363 | -112,443,541 |
