Circle the 5
Somewhere in front of you was a list of numbers. The instructions were asking you to break down the numbers and write them as a product of their prime factors. This is known as the prime factorization. The prime factorization of 30 is 2 x 3 x 5.
That's an infinite list. Numbers with three factors are the squares of prime numbers.
The prime factors of 51 are 3 and 17. Once you add itself and one, you have all the factors. (1,3,17,51)
The prime factors of a number by multiplying each other. You can also use exponents. a prime factorization is when you divide a number and see what all of the prime (odd) numbers make up that number. EX. 9 / \ 3 3 then you would circle the 3's because they are prime.
That's a prime factorization.
do the prime factorization of the 3 numbers. list the prime factors of all the 3 numbers. circle the factors that are common to the 3. multiply them. that number is the HCF
You cannot list all the potential prime factors. Any prime number can be a prime factor. There are an infinite number of prime numbers, so there are an infinite number of potential prime factors. If given a specific number, the prime factors for it can be listed.
List all the factors. Select the ones that are prime numbers.
You need to Writ edown all the factors.. :)
2 and 3
The product of all the common prime factors is the GCF. The product of all common factors would vary according to the list.
2 and 5 are the prime factors of 100.
2,3,5
The prime factors of 100 are 2 and 5 and 2*2*5*5 = 100
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
2 x 3 x 5
Prime numbers never stop, it is impossible to list them all.
