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 143,337,145, 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 | 143,337,145 | |
| -1 | -143,337,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,337,145.
Example:
1 x 143,337,145 = 143,337,145
and
-1 x -143,337,145 = 143,337,145
Notice both answers equal 143,337,145
With that explanation out of the way, let's continue. Next, we take the number 143,337,145 and divide it by 2:
143,337,145 ÷ 2 = 71,668,572.5
If the quotient is a whole number, then 2 and 71,668,572.5 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 | 143,337,145 | |
| -1 | -143,337,145 |
Now, we try dividing 143,337,145 by 3:
143,337,145 ÷ 3 = 47,779,048.3333
If the quotient is a whole number, then 3 and 47,779,048.3333 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 | 143,337,145 | |
| -1 | -143,337,145 |
Let's try dividing by 4:
143,337,145 ÷ 4 = 35,834,286.25
If the quotient is a whole number, then 4 and 35,834,286.25 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 | 143,337,145 | |
| -1 | 143,337,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,523 | 2,689 | 7,615 | 10,661 | 13,445 | 18,823 | 53,305 | 94,115 | 4,095,347 | 20,476,735 | 28,667,429 | 143,337,145 |
| -1 | -5 | -7 | -35 | -1,523 | -2,689 | -7,615 | -10,661 | -13,445 | -18,823 | -53,305 | -94,115 | -4,095,347 | -20,476,735 | -28,667,429 | -143,337,145 |
