How to Calculate Prime Factorization of 1120?

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 \( (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, ...) \).

\(1120\div \color{red}{2} = 560\)
\(560\div \color{red}{2} = 280\)
\(280\div \color{red}{2} = 140\)
\(140\div \color{red}{2} = 70\)
\(70\div \color{red}{2} = 35\)
\(35\div \color{red}{5} = 7\)
\(7\div \color{red}{7} = 1\)

Factorize\( (1120) = \) \(2\times 2\times 2\times 2\times 2\times 5\times 7\)
