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 47,020,225, 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 | 47,020,225 | |
| -1 | -47,020,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,020,225.
Example:
1 x 47,020,225 = 47,020,225
and
-1 x -47,020,225 = 47,020,225
Notice both answers equal 47,020,225
With that explanation out of the way, let's continue. Next, we take the number 47,020,225 and divide it by 2:
47,020,225 ÷ 2 = 23,510,112.5
If the quotient is a whole number, then 2 and 23,510,112.5 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 | 47,020,225 | |
| -1 | -47,020,225 |
Now, we try dividing 47,020,225 by 3:
47,020,225 ÷ 3 = 15,673,408.3333
If the quotient is a whole number, then 3 and 15,673,408.3333 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 | 47,020,225 | |
| -1 | -47,020,225 |
Let's try dividing by 4:
47,020,225 ÷ 4 = 11,755,056.25
If the quotient is a whole number, then 4 and 11,755,056.25 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 | 47,020,225 | |
| -1 | 47,020,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 139 | 175 | 695 | 973 | 1,933 | 3,475 | 4,865 | 9,665 | 13,531 | 24,325 | 48,325 | 67,655 | 268,687 | 338,275 | 1,343,435 | 1,880,809 | 6,717,175 | 9,404,045 | 47,020,225 |
| -1 | -5 | -7 | -25 | -35 | -139 | -175 | -695 | -973 | -1,933 | -3,475 | -4,865 | -9,665 | -13,531 | -24,325 | -48,325 | -67,655 | -268,687 | -338,275 | -1,343,435 | -1,880,809 | -6,717,175 | -9,404,045 | -47,020,225 |
