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.
The GCF is 18.
The Greatest Common Factor (GCF) of 36, 54, and 63 is: 9
The GCF is 9.
The GCF is 9.
The Greatest Common Factor (GCF) is: 9
The GCF of 54, 90, and 126 is 9
GCF(90, 63) = 9
The GCF is 3.
The GCF is: 9
The GCF is 9.
9
The GCF is 18.
The GCF is 18.
The GCF is 18.
The GCF is 6.
GCF is 18:54 = 18 x 372 = 18 x 490 = 18 x 5
The gcf of 27, 45, 63 and 90 is 18 Hope It Helps:)
