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 351,748,453, 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 | 351,748,453 | |
| -1 | -351,748,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,748,453.
Example:
1 x 351,748,453 = 351,748,453
and
-1 x -351,748,453 = 351,748,453
Notice both answers equal 351,748,453
With that explanation out of the way, let's continue. Next, we take the number 351,748,453 and divide it by 2:
351,748,453 ÷ 2 = 175,874,226.5
If the quotient is a whole number, then 2 and 175,874,226.5 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 | 351,748,453 | |
| -1 | -351,748,453 |
Now, we try dividing 351,748,453 by 3:
351,748,453 ÷ 3 = 117,249,484.3333
If the quotient is a whole number, then 3 and 117,249,484.3333 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 | 351,748,453 | |
| -1 | -351,748,453 |
Let's try dividing by 4:
351,748,453 ÷ 4 = 87,937,113.25
If the quotient is a whole number, then 4 and 87,937,113.25 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 | 351,748,453 | |
| -1 | 351,748,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 75,337 | 527,359 | 1,732,751 | 2,184,773 | 12,129,257 | 15,293,411 | 50,249,779 | 351,748,453 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -75,337 | -527,359 | -1,732,751 | -2,184,773 | -12,129,257 | -15,293,411 | -50,249,779 | -351,748,453 |
