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.
The greatest common factor of 54 , 90 = 18
The greatest common factor of 54 and 46 is 2.
The greatest common factor of 21 and 54 is 3. The greatest common factor is the highest number that divides exactly into two or more numbers. factors of 21: 1, 3, 7, 21 factors of 54: 1, 2, 3, 6, 9, 18, 27, 54 The greatest common factor of 21 and 54 is 3.
The Greatest Common Factor (GCF) is: 1
The greatest common factor of 54 and 100 is 2.
The greatest common factor of 54 and 80 is 2
The greatest common factor 54 and 66 is 23.
The greatest common factor of 54 , 90 = 18
The greatest common factor of 54 and 300 is 6.
The greatest common factor of 33 and 54 is 3.
The greatest common factor of 54 , 61 = 1
the greatest common factor of 16 and 54 is 2
The greatest common factor of 54 and 46 is 2.
The greatest common factor of 54 and 72 is 18.
the greatest common factor of 243 and 54 is 27.
The GCF is 2.
The GCF is 3.
