The greatest prime factor of both numbers is 3
The GCF of 18, 27, and 63 is 9. The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The prime factorization of 63 is 3*3*7 The GCF is 3*3 = 9.
To find the greatest common factor (GCF) of 18, 54, and 90, we first need to find the prime factorization of each number. The prime factorization of 18 is 2 * 3^2, the prime factorization of 54 is 2 * 3^3, and the prime factorization of 90 is 2 * 3^2 * 5. To find the GCF, we identify the common prime factors among the numbers, which are 2 and 3^2. Therefore, the GCF of 18, 54, and 90 is 2 * 3^2, which equals 18.
The GCF of 18, 27, and 99 is 9. The prime factorization of 18 is 2*3*3. The prime factorization of 27 is 3*3*3 The prime factorization of 99 is 3*3*11 So the GCF = 3*3 = 9.
The GCF of 18, 99, and 135 is 9.The prime factorization of 18 is 2*3*3The prime factorization of 99 is 3*3*11The prime factorization of 135 is 5*3*3*3Thus the GCF of 18, 99 and 135 is 9.
The greatest common factor of 18, 27, 36, and 48 is 3. The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The prime factorization of 36 is 2*2*3*3 The prime factorization of 48 is 2*2*2*2*3 The common factors are 1 and 3, and the GCF is 3.
The prime factorization of 18 is: 2 × 3 × 3
The GCF is 2. The prime factorization of 18 is 2x3x3 and the prime factorization of 16 is 2x2x2x2. They both have one 2 in common so that would be the greatest common factor.
The GCF of 16, 18 and 27 is 1. The prime factorization of 16 is 2*2*2*2 The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The numbers have no common factors except 1, so that is their GCF.
2 x 3 x 3 = 18
The prime factorization of 50 is 2x5x5 or 2 x 52. The prime factorization of 18 is 2x3x3 or 2 x 32. The prime factorization of 32 is 2x2x2x2x2 or 25.
The greatest common factor of 18, 27, and 36 is 9 The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The prime factorization of 36 is 2*2*3*3 The GCF is 3*3 = 9.
