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 142,234,225, 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 | 142,234,225 | |
| -1 | -142,234,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 142,234,225.
Example:
1 x 142,234,225 = 142,234,225
and
-1 x -142,234,225 = 142,234,225
Notice both answers equal 142,234,225
With that explanation out of the way, let's continue. Next, we take the number 142,234,225 and divide it by 2:
142,234,225 ÷ 2 = 71,117,112.5
If the quotient is a whole number, then 2 and 71,117,112.5 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 | 142,234,225 | |
| -1 | -142,234,225 |
Now, we try dividing 142,234,225 by 3:
142,234,225 ÷ 3 = 47,411,408.3333
If the quotient is a whole number, then 3 and 47,411,408.3333 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 | 142,234,225 | |
| -1 | -142,234,225 |
Let's try dividing by 4:
142,234,225 ÷ 4 = 35,558,556.25
If the quotient is a whole number, then 4 and 35,558,556.25 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 | 142,234,225 | |
| -1 | 142,234,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 373 | 1,865 | 2,179 | 2,611 | 9,325 | 10,895 | 13,055 | 15,253 | 54,475 | 65,275 | 76,265 | 381,325 | 812,767 | 4,063,835 | 5,689,369 | 20,319,175 | 28,446,845 | 142,234,225 |
| -1 | -5 | -7 | -25 | -35 | -175 | -373 | -1,865 | -2,179 | -2,611 | -9,325 | -10,895 | -13,055 | -15,253 | -54,475 | -65,275 | -76,265 | -381,325 | -812,767 | -4,063,835 | -5,689,369 | -20,319,175 | -28,446,845 | -142,234,225 |
