How do you express a whole number as a product of its primes?
This is called a prime factorization. 1. Start with the smallest prime that evenly divides into the number and divide. 2. Take the answer and divide by the smallest prime that evenly divides into the number .... repeat, until no longer divisible by any prime but itself. ex: 12 ..... 12 divide by 2 = 6 6 divide by 2 = 3 (3 is a prime) ans... 2x2x3
