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 70,404,145, 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 | 70,404,145 | |
| -1 | -70,404,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,404,145.
Example:
1 x 70,404,145 = 70,404,145
and
-1 x -70,404,145 = 70,404,145
Notice both answers equal 70,404,145
With that explanation out of the way, let's continue. Next, we take the number 70,404,145 and divide it by 2:
70,404,145 ÷ 2 = 35,202,072.5
If the quotient is a whole number, then 2 and 35,202,072.5 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 | 70,404,145 | |
| -1 | -70,404,145 |
Now, we try dividing 70,404,145 by 3:
70,404,145 ÷ 3 = 23,468,048.3333
If the quotient is a whole number, then 3 and 23,468,048.3333 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 | 70,404,145 | |
| -1 | -70,404,145 |
Let's try dividing by 4:
70,404,145 ÷ 4 = 17,601,036.25
If the quotient is a whole number, then 4 and 17,601,036.25 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 | 70,404,145 | |
| -1 | 70,404,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 601 | 3,005 | 3,347 | 4,207 | 16,735 | 21,035 | 23,429 | 117,145 | 2,011,547 | 10,057,735 | 14,080,829 | 70,404,145 |
| -1 | -5 | -7 | -35 | -601 | -3,005 | -3,347 | -4,207 | -16,735 | -21,035 | -23,429 | -117,145 | -2,011,547 | -10,057,735 | -14,080,829 | -70,404,145 |
