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 46,142,545, 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 | 46,142,545 | |
| -1 | -46,142,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,142,545.
Example:
1 x 46,142,545 = 46,142,545
and
-1 x -46,142,545 = 46,142,545
Notice both answers equal 46,142,545
With that explanation out of the way, let's continue. Next, we take the number 46,142,545 and divide it by 2:
46,142,545 ÷ 2 = 23,071,272.5
If the quotient is a whole number, then 2 and 23,071,272.5 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 | 46,142,545 | |
| -1 | -46,142,545 |
Now, we try dividing 46,142,545 by 3:
46,142,545 ÷ 3 = 15,380,848.3333
If the quotient is a whole number, then 3 and 15,380,848.3333 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 | 46,142,545 | |
| -1 | -46,142,545 |
Let's try dividing by 4:
46,142,545 ÷ 4 = 11,535,636.25
If the quotient is a whole number, then 4 and 11,535,636.25 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 | 46,142,545 | |
| -1 | 46,142,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 71 | 95 | 355 | 1,349 | 6,745 | 6,841 | 34,205 | 129,979 | 485,711 | 649,895 | 2,428,555 | 9,228,509 | 46,142,545 |
| -1 | -5 | -19 | -71 | -95 | -355 | -1,349 | -6,745 | -6,841 | -34,205 | -129,979 | -485,711 | -649,895 | -2,428,555 | -9,228,509 | -46,142,545 |
