This crate contains a small program to calculate the prime factors of positive integers, up to u64::MAX (18,446,744,073,709,551,615). You can install eb-prime-factor
using cargo install eb-prime-factor
if you have a working Rust toolchain (I recommend you use rustup) to get you there. Once installed, (assuming you have ~/.cargo/bin in your PATH), invoke with eb-prime-factor <some number>
.
