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 43,501,745, 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 | 43,501,745 | |
| -1 | -43,501,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,501,745.
Example:
1 x 43,501,745 = 43,501,745
and
-1 x -43,501,745 = 43,501,745
Notice both answers equal 43,501,745
With that explanation out of the way, let's continue. Next, we take the number 43,501,745 and divide it by 2:
43,501,745 ÷ 2 = 21,750,872.5
If the quotient is a whole number, then 2 and 21,750,872.5 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 | 43,501,745 | |
| -1 | -43,501,745 |
Now, we try dividing 43,501,745 by 3:
43,501,745 ÷ 3 = 14,500,581.6667
If the quotient is a whole number, then 3 and 14,500,581.6667 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 | 43,501,745 | |
| -1 | -43,501,745 |
Let's try dividing by 4:
43,501,745 ÷ 4 = 10,875,436.25
If the quotient is a whole number, then 4 and 10,875,436.25 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 | 43,501,745 | |
| -1 | 43,501,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 15,733 | 78,665 | 110,131 | 550,655 | 1,242,907 | 6,214,535 | 8,700,349 | 43,501,745 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -15,733 | -78,665 | -110,131 | -550,655 | -1,242,907 | -6,214,535 | -8,700,349 | -43,501,745 |
