Prime factorization is when you break down the factors of 29 to just the prime factors and expressing 29 as a product of those prime factors.
In this case, because 29 is a prime number, we can simply state the primary factorization as 29.
For most numbers, we would take the smallest prime factor that is larger than 1 to start to break down the focus number. In this case, the smallest prime factor larger than 1 is 29.
29 ÷ 29 = 1
If we divide 29 by 29, we simply get 1, which can’t be broken down any further.
So, the prime factorization of 29 is just 29.
