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 43,019,053, 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 | 43,019,053 | |
| -1 | -43,019,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,019,053.
Example:
1 x 43,019,053 = 43,019,053
and
-1 x -43,019,053 = 43,019,053
Notice both answers equal 43,019,053
With that explanation out of the way, let's continue. Next, we take the number 43,019,053 and divide it by 2:
43,019,053 ÷ 2 = 21,509,526.5
If the quotient is a whole number, then 2 and 21,509,526.5 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 | 43,019,053 | |
| -1 | -43,019,053 |
Now, we try dividing 43,019,053 by 3:
43,019,053 ÷ 3 = 14,339,684.3333
If the quotient is a whole number, then 3 and 14,339,684.3333 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 | 43,019,053 | |
| -1 | -43,019,053 |
Let's try dividing by 4:
43,019,053 ÷ 4 = 10,754,763.25
If the quotient is a whole number, then 4 and 10,754,763.25 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 | 43,019,053 | |
| -1 | 43,019,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 11,887 | 83,209 | 130,757 | 558,689 | 915,299 | 3,910,823 | 6,145,579 | 43,019,053 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -11,887 | -83,209 | -130,757 | -558,689 | -915,299 | -3,910,823 | -6,145,579 | -43,019,053 |
