What is the LCM of 39,9,117

That settles it....... 117 is the Most Common Multiple (answer)........

Write each number in factored form:

39  =  3 x 13

9  =  3 x 3

117  =  3 x 39  =  3 x 3 x 13

Take each factor the greatest number of times in each number;  3 x 3 x 13  =  117.

Each number, 13, 3, and 117 will divide into 117 without a remaider (and, no smaller number will work) ; therefore, it is the least common multiple.

39=3*13

117=3*3*13=3*39

so 117 is a multiple of 39

9=3*3  so 117 is a multiple of 9

so the lowest common multiple is 117

3 = 3 x 1

39 =13 x 3

117 = 3² x 13

So taking each different factor with the higest power, we have

3² x 13  = 117   = LCM
