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 70,133,371, 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 | 70,133,371 | |
| -1 | -70,133,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,133,371.
Example:
1 x 70,133,371 = 70,133,371
and
-1 x -70,133,371 = 70,133,371
Notice both answers equal 70,133,371
With that explanation out of the way, let's continue. Next, we take the number 70,133,371 and divide it by 2:
70,133,371 ÷ 2 = 35,066,685.5
If the quotient is a whole number, then 2 and 35,066,685.5 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 | 70,133,371 | |
| -1 | -70,133,371 |
Now, we try dividing 70,133,371 by 3:
70,133,371 ÷ 3 = 23,377,790.3333
If the quotient is a whole number, then 3 and 23,377,790.3333 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 | 70,133,371 | |
| -1 | -70,133,371 |
Let's try dividing by 4:
70,133,371 ÷ 4 = 17,533,342.75
If the quotient is a whole number, then 4 and 17,533,342.75 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 | 70,133,371 | |
| -1 | 70,133,371 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 199 | 253 | 1,393 | 1,771 | 2,189 | 4,577 | 15,323 | 32,039 | 39,601 | 50,347 | 277,207 | 352,429 | 435,611 | 910,823 | 3,049,277 | 6,375,761 | 10,019,053 | 70,133,371 |
| -1 | -7 | -11 | -23 | -77 | -161 | -199 | -253 | -1,393 | -1,771 | -2,189 | -4,577 | -15,323 | -32,039 | -39,601 | -50,347 | -277,207 | -352,429 | -435,611 | -910,823 | -3,049,277 | -6,375,761 | -10,019,053 | -70,133,371 |
