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 74,656,483, 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 | 74,656,483 | |
| -1 | -74,656,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,656,483.
Example:
1 x 74,656,483 = 74,656,483
and
-1 x -74,656,483 = 74,656,483
Notice both answers equal 74,656,483
With that explanation out of the way, let's continue. Next, we take the number 74,656,483 and divide it by 2:
74,656,483 ÷ 2 = 37,328,241.5
If the quotient is a whole number, then 2 and 37,328,241.5 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 | 74,656,483 | |
| -1 | -74,656,483 |
Now, we try dividing 74,656,483 by 3:
74,656,483 ÷ 3 = 24,885,494.3333
If the quotient is a whole number, then 3 and 24,885,494.3333 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 | 74,656,483 | |
| -1 | -74,656,483 |
Let's try dividing by 4:
74,656,483 ÷ 4 = 18,664,120.75
If the quotient is a whole number, then 4 and 18,664,120.75 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 | 74,656,483 | |
| -1 | 74,656,483 |
If you did it right, you will end up with this table:
| 1 | 11 | 139 | 157 | 311 | 1,529 | 1,727 | 3,421 | 21,823 | 43,229 | 48,827 | 240,053 | 475,519 | 537,097 | 6,786,953 | 74,656,483 |
| -1 | -11 | -139 | -157 | -311 | -1,529 | -1,727 | -3,421 | -21,823 | -43,229 | -48,827 | -240,053 | -475,519 | -537,097 | -6,786,953 | -74,656,483 |
