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 146,425,279, 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 | 146,425,279 | |
| -1 | -146,425,279 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,425,279.
Example:
1 x 146,425,279 = 146,425,279
and
-1 x -146,425,279 = 146,425,279
Notice both answers equal 146,425,279
With that explanation out of the way, let's continue. Next, we take the number 146,425,279 and divide it by 2:
146,425,279 ÷ 2 = 73,212,639.5
If the quotient is a whole number, then 2 and 73,212,639.5 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 | 146,425,279 | |
| -1 | -146,425,279 |
Now, we try dividing 146,425,279 by 3:
146,425,279 ÷ 3 = 48,808,426.3333
If the quotient is a whole number, then 3 and 48,808,426.3333 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 | 146,425,279 | |
| -1 | -146,425,279 |
Let's try dividing by 4:
146,425,279 ÷ 4 = 36,606,319.75
If the quotient is a whole number, then 4 and 36,606,319.75 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 | 146,425,279 | |
| -1 | 146,425,279 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 1,001 | 7,007 | 20,897 | 146,279 | 229,867 | 271,661 | 1,023,953 | 1,609,069 | 1,901,627 | 2,988,271 | 11,263,483 | 13,311,389 | 20,917,897 | 146,425,279 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -1,001 | -7,007 | -20,897 | -146,279 | -229,867 | -271,661 | -1,023,953 | -1,609,069 | -1,901,627 | -2,988,271 | -11,263,483 | -13,311,389 | -20,917,897 | -146,425,279 |
