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 43,025,191, 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 | 43,025,191 | |
| -1 | -43,025,191 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,025,191.
Example:
1 x 43,025,191 = 43,025,191
and
-1 x -43,025,191 = 43,025,191
Notice both answers equal 43,025,191
With that explanation out of the way, let's continue. Next, we take the number 43,025,191 and divide it by 2:
43,025,191 ÷ 2 = 21,512,595.5
If the quotient is a whole number, then 2 and 21,512,595.5 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 | 43,025,191 | |
| -1 | -43,025,191 |
Now, we try dividing 43,025,191 by 3:
43,025,191 ÷ 3 = 14,341,730.3333
If the quotient is a whole number, then 3 and 14,341,730.3333 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 | 43,025,191 | |
| -1 | -43,025,191 |
Let's try dividing by 4:
43,025,191 ÷ 4 = 10,756,297.75
If the quotient is a whole number, then 4 and 10,756,297.75 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 | 43,025,191 | |
| -1 | 43,025,191 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 61 | 407 | 671 | 1,733 | 2,257 | 19,063 | 24,827 | 64,121 | 105,713 | 705,331 | 1,162,843 | 3,911,381 | 43,025,191 |
| -1 | -11 | -37 | -61 | -407 | -671 | -1,733 | -2,257 | -19,063 | -24,827 | -64,121 | -105,713 | -705,331 | -1,162,843 | -3,911,381 | -43,025,191 |
