Webb29 mars 2024 · The first step is to divide the number 42 with the smallest prime factor, i.e. 2. 42 ÷ 2 = 21 Now, check whether 21 can be further divided by 2 or not. 21 ÷ 2 = 10.5 … WebbThe purpose is ro return the smallest prime factor of number n. At first it does checks for trivial/simple cases (whether n is divisable by 2,3,5, the first 3 prime numbers) Then the loop starts fromt the next prime number (=7) and checks up to sqrt (n) (which is enough, but not the most efficient check for factoring n)

Prime Factorization of 42 with a Factor Tree - MathOnDemand.com

WebbThe prime factorization of 42 is explained below: Divide the number 42 with the smallest prime factor 2. 42 ÷ 2 = 21. Check if 21 can be further divided by 2 or not. 21 ÷ 2 = 10.5. Since 21 is not completely divisible by 2, we will proceed to the next prime number, which is 3. Dividing 21 by 3, 21 ÷ 3 = 7.
