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 43,020,445, 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 | 43,020,445 | |
| -1 | -43,020,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,020,445.
Example:
1 x 43,020,445 = 43,020,445
and
-1 x -43,020,445 = 43,020,445
Notice both answers equal 43,020,445
With that explanation out of the way, let's continue. Next, we take the number 43,020,445 and divide it by 2:
43,020,445 ÷ 2 = 21,510,222.5
If the quotient is a whole number, then 2 and 21,510,222.5 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 | 43,020,445 | |
| -1 | -43,020,445 |
Now, we try dividing 43,020,445 by 3:
43,020,445 ÷ 3 = 14,340,148.3333
If the quotient is a whole number, then 3 and 14,340,148.3333 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 | 43,020,445 | |
| -1 | -43,020,445 |
Let's try dividing by 4:
43,020,445 ÷ 4 = 10,755,111.25
If the quotient is a whole number, then 4 and 10,755,111.25 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 | 43,020,445 | |
| -1 | 43,020,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 505 | 1,313 | 6,553 | 6,565 | 32,765 | 85,189 | 425,945 | 661,853 | 3,309,265 | 8,604,089 | 43,020,445 |
| -1 | -5 | -13 | -65 | -101 | -505 | -1,313 | -6,553 | -6,565 | -32,765 | -85,189 | -425,945 | -661,853 | -3,309,265 | -8,604,089 | -43,020,445 |
