Prime factorization of $$$976$$$
Your Input
Find the prime factorization of $$$976$$$.
Solution
Start with the number $$$2$$$.
Determine whether $$$976$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$976$$$ by $$${\color{green}2}$$$: $$$\frac{976}{2} = {\color{red}488}$$$.
Determine whether $$$488$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$488$$$ by $$${\color{green}2}$$$: $$$\frac{488}{2} = {\color{red}244}$$$.
Determine whether $$$244$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$244$$$ by $$${\color{green}2}$$$: $$$\frac{244}{2} = {\color{red}122}$$$.
Determine whether $$$122$$$ is divisible by $$$2$$$.
It is divisible, thus, divide $$$122$$$ by $$${\color{green}2}$$$: $$$\frac{122}{2} = {\color{red}61}$$$.
The prime number $$${\color{green}61}$$$ has no other factors then $$$1$$$ and $$${\color{green}61}$$$: $$$\frac{61}{61} = {\color{red}1}$$$.
Since we have obtained $$$1$$$, we are done.
Now, just count the number of occurences of the divisors (green numbers), and write down the prime factorization: $$$976 = 2^{4} \cdot 61$$$.
Answer
The prime factorization is $$$976 = 2^{4} \cdot 61$$$A.
