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 112,562,615, 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 | 112,562,615 | |
| -1 | -112,562,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,562,615.
Example:
1 x 112,562,615 = 112,562,615
and
-1 x -112,562,615 = 112,562,615
Notice both answers equal 112,562,615
With that explanation out of the way, let's continue. Next, we take the number 112,562,615 and divide it by 2:
112,562,615 ÷ 2 = 56,281,307.5
If the quotient is a whole number, then 2 and 56,281,307.5 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 | 112,562,615 | |
| -1 | -112,562,615 |
Now, we try dividing 112,562,615 by 3:
112,562,615 ÷ 3 = 37,520,871.6667
If the quotient is a whole number, then 3 and 37,520,871.6667 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 | 112,562,615 | |
| -1 | -112,562,615 |
Let's try dividing by 4:
112,562,615 ÷ 4 = 28,140,653.75
If the quotient is a whole number, then 4 and 28,140,653.75 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 | 112,562,615 | |
| -1 | 112,562,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 673 | 3,041 | 3,365 | 7,403 | 15,205 | 33,451 | 37,015 | 167,255 | 2,046,593 | 10,232,965 | 22,512,523 | 112,562,615 |
| -1 | -5 | -11 | -55 | -673 | -3,041 | -3,365 | -7,403 | -15,205 | -33,451 | -37,015 | -167,255 | -2,046,593 | -10,232,965 | -22,512,523 | -112,562,615 |
