It is 3 that is a common prime factor to both numbers
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
The common prime factors of 27 and 117 are the prime numbers that can divide both 27 and 117 without leaving a remainder. The prime factorization of 27 is 3 x 3 x 3, and the prime factorization of 117 is 3 x 3 x 13. The only common prime factor between 27 and 117 is 3, as it is the only prime number that appears in the factorization of 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.

3 and 31 (both prime)
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
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.
