The prime factorization of 18 is 2 x 3 x 3, so 2 and 3 are both prime factors of 18.
194 2 x 97 Since both 2 and 97 are prime numbers, the prime factorization tree is complete.
Writing down all the factors of both numbers requires too much time so it is not a good idea to find solution by writing each factor of both numbers. Method of prime factorization is one of the good methods to find GCF. Prime factorization is like breaking a number into other numbers, prime numbers, and this factorization is unique. Prime factorization is like a blueprint for numbers. Prime factorization of 1820 = 22 x 5 x 7 x 13 Prime factorization of 637 = 7 x 7 x 13 7, 13 and 7x13 are common in the prime factorization of both numbers, but 7x13 is the greatest among these numbers. So, 7x13 = 91 is the GCF of 1820 and 637.

nope it isn't : 11 x 17 = 187.No, 187 is not a prime number. 11 times 17 equals 187. Both are prime numbers, so the prime factorization of 187 is 11 X 17.
3 x 7 = 21, since both factors are prime, that is the prime factorization of 21.
217 = 7x31 and both of those are primes for that is its prime factorization! Dr. Chuck
they are both numbers
To find the prime factorization of a number, start with any factor pair of that number and keep factoring the composite numbers until all factors are prime. 55 5 x 11 = 55 Both factors are prime, so that is the prime factorization.

58=2*29; both 2 and 29 are prime, thus this is the prime factorization. In general, a prime factorization is a list of primes that comprise the number. For instance, 100: 100=2*50=2*2*25=2*2*5*5 => prime factorization is 2^2*5^2
3 and 31 (both prime)
34 is 17 x 2 and they are both primes, so 17x2 is the prime factorization of 34
7 x 11 = 77 Since 7 and 11 are both prime, that's it.
Prime FactorizationA factorization is prime when all the factors are prime numbers (those which only have itself and 1 as factors).For example,2 X 4 and 2 X 2 X 2 are both factorizations of 8. Only 2 X 2 X 2 is a prime factorization because 2 X 4 includes the composite number 4.
