Divisibility rules and prime factorization

A number is divisible by 2 if its last digit is even; by 3 if its digit sum is divisible by 3; by 5 if it ends in 0 or 5; by 9 if its digit sum is divisible by 9; by 10 if it ends in 0. Prime factorization decomposes a number into its prime building blocks — useful for computing GCDs, LCMs, and solving modular arithmetic problems.
