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 145,537,483, 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 | 145,537,483 | |
| -1 | -145,537,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,537,483.
Example:
1 x 145,537,483 = 145,537,483
and
-1 x -145,537,483 = 145,537,483
Notice both answers equal 145,537,483
With that explanation out of the way, let's continue. Next, we take the number 145,537,483 and divide it by 2:
145,537,483 ÷ 2 = 72,768,741.5
If the quotient is a whole number, then 2 and 72,768,741.5 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 | 145,537,483 | |
| -1 | -145,537,483 |
Now, we try dividing 145,537,483 by 3:
145,537,483 ÷ 3 = 48,512,494.3333
If the quotient is a whole number, then 3 and 48,512,494.3333 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 | 145,537,483 | |
| -1 | -145,537,483 |
Let's try dividing by 4:
145,537,483 ÷ 4 = 36,384,370.75
If the quotient is a whole number, then 4 and 36,384,370.75 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 | 145,537,483 | |
| -1 | 145,537,483 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 767 | 5,369 | 27,107 | 189,749 | 352,391 | 1,599,313 | 2,466,737 | 11,195,191 | 20,791,069 | 145,537,483 |
| -1 | -7 | -13 | -59 | -91 | -413 | -767 | -5,369 | -27,107 | -189,749 | -352,391 | -1,599,313 | -2,466,737 | -11,195,191 | -20,791,069 | -145,537,483 |
