Practice the worksheet on L.C.M. of monomials. The questions are based on finding the lowest common multiple of two or more monomials. We know, the lowest common multiple (L.C.M.) of two or more monomials is the monomial of lowest dimensions which is divisible by each of them without remainder.

If the monomials have numerical coefficients, find by Arithmetic their least common measure, and prefix it as a coefficient to the algebraical lowest common multiple.

(i) the least common measure of the numerical coefficients;

(ii) the lowest power of each letter which is divisible by every power of that letter occurring in the given expressions.

**1. Find the lowest common multiple (L.C.M.) ****of the two monomials:**

(ii) a

(iii) 3a

(iv) 5x

(v) 3x

(vi) 12mn and 8pq
