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 70,227,553, 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 | 70,227,553 | |
| -1 | -70,227,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,227,553.
Example:
1 x 70,227,553 = 70,227,553
and
-1 x -70,227,553 = 70,227,553
Notice both answers equal 70,227,553
With that explanation out of the way, let's continue. Next, we take the number 70,227,553 and divide it by 2:
70,227,553 ÷ 2 = 35,113,776.5
If the quotient is a whole number, then 2 and 35,113,776.5 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 | 70,227,553 | |
| -1 | -70,227,553 |
Now, we try dividing 70,227,553 by 3:
70,227,553 ÷ 3 = 23,409,184.3333
If the quotient is a whole number, then 3 and 23,409,184.3333 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 | 70,227,553 | |
| -1 | -70,227,553 |
Let's try dividing by 4:
70,227,553 ÷ 4 = 17,556,888.25
If the quotient is a whole number, then 4 and 17,556,888.25 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 | 70,227,553 | |
| -1 | 70,227,553 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 121 | 209 | 1,331 | 2,299 | 2,777 | 25,289 | 30,547 | 52,763 | 336,017 | 580,393 | 3,696,187 | 6,384,323 | 70,227,553 |
| -1 | -11 | -19 | -121 | -209 | -1,331 | -2,299 | -2,777 | -25,289 | -30,547 | -52,763 | -336,017 | -580,393 | -3,696,187 | -6,384,323 | -70,227,553 |
