The GCF is 3.
The Greatest Common Factor (GCF) of 21 and 90 is 3.
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 The factors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126 The Greatest Common Factor: GCF = 18
The GCF is 3.
2 x 3 x 3 x 3 = 54 2 x 3 x 3 x 5 = 90 2 x 3 x 3 = 18, the GCF
3 3*7=21 3*30=90 * * * * * That is the Greatest Common Factor, GCF, not the LCM. LCM(21, 90) = 630
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 is 3.
They are 1 and 3 .Note: Those are also the least common factors of 9, 21, and 54 .
It is 18 which the highest number that will divide into both of them with no remainder
