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 43,003,555, 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 | 43,003,555 | |
| -1 | -43,003,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,003,555.
Example:
1 x 43,003,555 = 43,003,555
and
-1 x -43,003,555 = 43,003,555
Notice both answers equal 43,003,555
With that explanation out of the way, let's continue. Next, we take the number 43,003,555 and divide it by 2:
43,003,555 ÷ 2 = 21,501,777.5
If the quotient is a whole number, then 2 and 21,501,777.5 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 | 43,003,555 | |
| -1 | -43,003,555 |
Now, we try dividing 43,003,555 by 3:
43,003,555 ÷ 3 = 14,334,518.3333
If the quotient is a whole number, then 3 and 14,334,518.3333 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 | 43,003,555 | |
| -1 | -43,003,555 |
Let's try dividing by 4:
43,003,555 ÷ 4 = 10,750,888.75
If the quotient is a whole number, then 4 and 10,750,888.75 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 | 43,003,555 | |
| -1 | 43,003,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 64,667 | 323,335 | 452,669 | 1,228,673 | 2,263,345 | 6,143,365 | 8,600,711 | 43,003,555 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -64,667 | -323,335 | -452,669 | -1,228,673 | -2,263,345 | -6,143,365 | -8,600,711 | -43,003,555 |
