They can be: 2*27 = 54
54 = 1 x 54, 2 x 27, 3 x 18, 6 x 9
Multiply prime squares by themselves. 24, 34, 54 all have five factors.
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
These are some numbers you can multiply to get 270: 1 × 270 2 x 135 3 x 90 5 x 54 6 x 45 9 x 30 10 x 27
