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 145,092,431, 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 | 145,092,431 | |
| -1 | -145,092,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,092,431.
Example:
1 x 145,092,431 = 145,092,431
and
-1 x -145,092,431 = 145,092,431
Notice both answers equal 145,092,431
With that explanation out of the way, let's continue. Next, we take the number 145,092,431 and divide it by 2:
145,092,431 ÷ 2 = 72,546,215.5
If the quotient is a whole number, then 2 and 72,546,215.5 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 | 145,092,431 | |
| -1 | -145,092,431 |
Now, we try dividing 145,092,431 by 3:
145,092,431 ÷ 3 = 48,364,143.6667
If the quotient is a whole number, then 3 and 48,364,143.6667 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 | 145,092,431 | |
| -1 | -145,092,431 |
Let's try dividing by 4:
145,092,431 ÷ 4 = 36,273,107.75
If the quotient is a whole number, then 4 and 36,273,107.75 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 | 145,092,431 | |
| -1 | 145,092,431 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 47 | 121 | 341 | 517 | 823 | 1,457 | 3,751 | 5,687 | 9,053 | 16,027 | 25,513 | 38,681 | 99,583 | 176,297 | 280,643 | 425,491 | 1,199,111 | 3,087,073 | 4,680,401 | 13,190,221 | 145,092,431 |
| -1 | -11 | -31 | -47 | -121 | -341 | -517 | -823 | -1,457 | -3,751 | -5,687 | -9,053 | -16,027 | -25,513 | -38,681 | -99,583 | -176,297 | -280,643 | -425,491 | -1,199,111 | -3,087,073 | -4,680,401 | -13,190,221 | -145,092,431 |
