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 46,172,203, 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 | 46,172,203 | |
| -1 | -46,172,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,172,203.
Example:
1 x 46,172,203 = 46,172,203
and
-1 x -46,172,203 = 46,172,203
Notice both answers equal 46,172,203
With that explanation out of the way, let's continue. Next, we take the number 46,172,203 and divide it by 2:
46,172,203 ÷ 2 = 23,086,101.5
If the quotient is a whole number, then 2 and 23,086,101.5 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 | 46,172,203 | |
| -1 | -46,172,203 |
Now, we try dividing 46,172,203 by 3:
46,172,203 ÷ 3 = 15,390,734.3333
If the quotient is a whole number, then 3 and 15,390,734.3333 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 | 46,172,203 | |
| -1 | -46,172,203 |
Let's try dividing by 4:
46,172,203 ÷ 4 = 11,543,050.75
If the quotient is a whole number, then 4 and 11,543,050.75 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 | 46,172,203 | |
| -1 | 46,172,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 251 | 1,757 | 2,389 | 2,761 | 16,723 | 19,327 | 26,279 | 183,953 | 599,639 | 4,197,473 | 6,596,029 | 46,172,203 |
| -1 | -7 | -11 | -77 | -251 | -1,757 | -2,389 | -2,761 | -16,723 | -19,327 | -26,279 | -183,953 | -599,639 | -4,197,473 | -6,596,029 | -46,172,203 |
