Step 1When working with HCF and/or LCM, write each number as the product of its &#039; factors. That will tell you everything you need to know about a number.Look for all the common factors:                    36        =        2        ×        2        ×        3        ×        3                                                  54            =            2            ×            3            ×            3            ×            3                    _                                    H        C        F        =        2        ×        3        ×        3        =        18            The highest common factor is the product of all the common factors.This is a very quick and effective method, especially if you are working with large numbers where you might not know all of the factors.The product of the &#039; factors will tell you whether a number is a power, like a square or a cube.You can also use the &#039; factors to determine all the other factors as well.

Step 1Because      3    ⋅    18    =    54        2    ⋅    18    =    36  AlsoThe factors of 54:      1    ,    2    ,    3    ,    6    ,    9    ,    18    ,    27    ,    54    -    1    ,    -    2    ,    -    3    ,    -    6    ,    -    9    ,    -    18    ,    -    27    ,    -    54  The factors of 36:      1    ,    2    ,    3    ,    4    ,    6    ,    9    ,    12    ,    18    ,    36    -    1    ,    -    2    ,    -    3    ,    -    4    ,    -    6    ,    -    9    ,    -    12    ,    -    18    ,    -    36  The greatest common factor of 54 and   36  =  18
