What is the greatest common factor of 18 54 90?

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.


What is the GCF of 32 90 and 30?

Prime factorization of 32 = 2x2x2x2x2 Prime factorization of 90 = 2x3x3x5 Prime factorization of 30 = 2x3x5 What is common in the prime factorization of the numbers? Only 2 is common, so GCF is 2.


What is the GCF of 54 90 and 63?

To find the Greatest Common Factor (GCF) of 54, 90, and 63, we need to first find the prime factorization of each number. The prime factorization of 54 is 2 x 3 x 3 x 3 = 2 x 3^3. The prime factorization of 90 is 2 x 3 x 3 x 5 = 2 x 3^2 x 5. The prime factorization of 63 is 3 x 3 x 7 = 3^2 x 7. To find the GCF, we look for the common factors in the prime factorizations, which are 3 squared or 9. Therefore, the GCF of 54, 90, and 63 is 9.
