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 361,440,553, 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 | 361,440,553 | |
| -1 | -361,440,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 361,440,553.
Example:
1 x 361,440,553 = 361,440,553
and
-1 x -361,440,553 = 361,440,553
Notice both answers equal 361,440,553
With that explanation out of the way, let's continue. Next, we take the number 361,440,553 and divide it by 2:
361,440,553 ÷ 2 = 180,720,276.5
If the quotient is a whole number, then 2 and 180,720,276.5 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 | 361,440,553 | |
| -1 | -361,440,553 |
Now, we try dividing 361,440,553 by 3:
361,440,553 ÷ 3 = 120,480,184.3333
If the quotient is a whole number, then 3 and 120,480,184.3333 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 | 361,440,553 | |
| -1 | -361,440,553 |
Let's try dividing by 4:
361,440,553 ÷ 4 = 90,360,138.25
If the quotient is a whole number, then 4 and 90,360,138.25 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 | 361,440,553 | |
| -1 | 361,440,553 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 439 | 2,549 | 7,463 | 8,341 | 43,333 | 48,431 | 141,797 | 823,327 | 1,119,011 | 19,023,187 | 21,261,209 | 361,440,553 |
| -1 | -17 | -19 | -323 | -439 | -2,549 | -7,463 | -8,341 | -43,333 | -48,431 | -141,797 | -823,327 | -1,119,011 | -19,023,187 | -21,261,209 | -361,440,553 |
