How to Calculate Prime Factorization of 320?

The main method of prime factorization is start dividing the number by the any divisible prime numbers until the only numbers left are prime numbers \( (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, ...) \).

\(320\div \color{red}{2} = 160\)
\(160\div \color{red}{2} = 80\)
\(80\div \color{red}{2} = 40\)
\(40\div \color{red}{2} = 20\)
\(20\div \color{red}{2} = 10\)
\(10\div \color{red}{2} = 5\)
\(5\div \color{red}{5} = 1\)

Factorize\( (320) = \) \(2\times 2\times 2\times 2\times 2\times 2\times 5\)
