What does the prime factorization mean in math for 5th grade?
Prime factorization is a way of writing a composite number as the product of its prime factors. The prime factors of 6 are 2 and 3. 2 x 3 is the prime factorization of 6.
Why is the prime factor 6?
To find the prime factorization of a number: Begin by listing 2 numbers that will multiply to make your number. 6 = 2 * 3 Can we find 2 numbers to multiply to make 2, or 3? (aside from 1) No, of course not. In fact, 2 and 3 are prime. Once you have all primes, you can stop. 6 = 2 * 3 2 * 3 is the prime factorization of 6.
How do you find the prime factorization of 18 and 21?
Draw the prime factorization table and put both the numbers on it. Find common prime factors and divide both of them writing the products down. Do this until the quotients are either 1 or any prime number. Write down all the factors used and it will be the prime factorization. Multiply them and you will find the LCM of the numbers. Here, 18,21 6,7...................(/3) Prime factorization=6*7*3 LCM=42*3=126
How do you do the prime factorization of 42?
You find the prime factorization of 42 like this. You think what 2 number multiplied together give you 42: 6x7 7 is prime because the only factors it has is 1 and itself. 6 can be broken into 3x2. So you currently have 7x3x2. All these numbers are prime so you just found the prime factorization!
How do you write 6 000 000 000 using prime factorization?
The prime factorization of 6,000,000,000 is: 210 × 3 × 59.
