The prime factorization for 21 is: 3x73 x 7 = 21
The prime factorization of 18 is 2*3*3 or 2 * 3^2
As opposed to... Forget that. The prime factorization of 18 is 2 x 3 x 3.
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
14*21
18 = 2*3*3 21 = 3*7
18 = 21 x 32
18 = 21 x 32
The prime factorization for 21 is: 3x73 x 7 = 21
18 = 21 x 32
18 = 21 x 32
3 x 7 = 21, since both factors are prime, that is the prime factorization of 21.
18 = 2 x 3 x 5 x 19 21 = 3 x 7
The prime factorization of 18 is: 2 × 3 × 3
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 18 and 21, you can list the factors of each number: 18 (1, 2, 3, 6, 9, 18) and 21 (1, 3, 7, 21). The common factors are 1 and 3, and the greatest common factor is 3.
The prime factorization of 21 is 3 x 7.
