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 70,763,077, 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 | 70,763,077 | |
| -1 | -70,763,077 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,763,077.
Example:
1 x 70,763,077 = 70,763,077
and
-1 x -70,763,077 = 70,763,077
Notice both answers equal 70,763,077
With that explanation out of the way, let's continue. Next, we take the number 70,763,077 and divide it by 2:
70,763,077 ÷ 2 = 35,381,538.5
If the quotient is a whole number, then 2 and 35,381,538.5 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 | 70,763,077 | |
| -1 | -70,763,077 |
Now, we try dividing 70,763,077 by 3:
70,763,077 ÷ 3 = 23,587,692.3333
If the quotient is a whole number, then 3 and 23,587,692.3333 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 | 70,763,077 | |
| -1 | -70,763,077 |
Let's try dividing by 4:
70,763,077 ÷ 4 = 17,690,769.25
If the quotient is a whole number, then 4 and 17,690,769.25 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 | 70,763,077 | |
| -1 | 70,763,077 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 167 | 1,169 | 1,837 | 5,503 | 12,859 | 38,521 | 60,533 | 423,731 | 919,001 | 6,433,007 | 10,109,011 | 70,763,077 |
| -1 | -7 | -11 | -77 | -167 | -1,169 | -1,837 | -5,503 | -12,859 | -38,521 | -60,533 | -423,731 | -919,001 | -6,433,007 | -10,109,011 | -70,763,077 |
