Free Prime Factorization Calculator
Go straight to calculator Let's say something about PRIME numbers first:  are whole numbers that
 can't be divided by any number  other than 1 and itself (with no remainder)
 are always odd numbers (but not all odd numbers are primes)
 are greater than 1 (1 is NOT a prime number)
On the other hand, every composite number can be factored to primes, and this is what this calculator is for.
Now let's remind ourselfs what are FACTORS: 3  ×  5  =  15  factor  ×  factor  =  multiple (product) 
Composites examples:  12 = 3 × 2 × 2 = 3 × 2^{2}
=> 12 is divisible by 2, 3, 4 and 6 (apart from 1 and 12)  15 = 3 × 5
=> 15 is divisible by 3 and 5 (apart from 1 and 15)  54 = 2 × 3 × 3 × 3 = 2 × 3^{3}
=> 54 is divisible by 1, 2, 3, 6, 9, 18 and 27 (apart from 1 and 54)
Primes examples:  5 = 5 × 1
=> is divisible only by 5 and 1  11 = 11 × 1
=> is divisible only by 11 and 1  29 = 29 × 1
=> is divisible only by 29 and 1
