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 61,603,453, 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 | 61,603,453 | |
| -1 | -61,603,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,603,453.
Example:
1 x 61,603,453 = 61,603,453
and
-1 x -61,603,453 = 61,603,453
Notice both answers equal 61,603,453
With that explanation out of the way, let's continue. Next, we take the number 61,603,453 and divide it by 2:
61,603,453 ÷ 2 = 30,801,726.5
If the quotient is a whole number, then 2 and 30,801,726.5 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 | 61,603,453 | |
| -1 | -61,603,453 |
Now, we try dividing 61,603,453 by 3:
61,603,453 ÷ 3 = 20,534,484.3333
If the quotient is a whole number, then 3 and 20,534,484.3333 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 | 61,603,453 | |
| -1 | -61,603,453 |
Let's try dividing by 4:
61,603,453 ÷ 4 = 15,400,863.25
If the quotient is a whole number, then 4 and 15,400,863.25 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 | 61,603,453 | |
| -1 | 61,603,453 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 29 | 437 | 551 | 667 | 4,861 | 12,673 | 92,359 | 111,803 | 140,969 | 2,124,257 | 2,678,411 | 3,242,287 | 61,603,453 |
| -1 | -19 | -23 | -29 | -437 | -551 | -667 | -4,861 | -12,673 | -92,359 | -111,803 | -140,969 | -2,124,257 | -2,678,411 | -3,242,287 | -61,603,453 |
