To work this out, you first have to break the two numbers into their prime factors: 50 = 2x5x5 54 = 2x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore the GCF of 50 and 54 is 2.
54 27,2 9,3,2 3,3,3,2 2 x 3 x 3 x 3 = 54
The greatest common factor (GCF) of 54 and 105 is 3. To find the GCF, you need to determine the prime factors of each number. The prime factorization of 54 is 2 * 3^3, and the prime factorization of 105 is 3 * 5 * 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 3.
