LCM worksheets for kids to practice LCM problems. The Lowest Common Multiple (L.C.M) is the smallest number that is a common multiple of two or more numbers. The simple method of finding the L.C.M of smaller numbers is to write down the multiples of the larger number until one of them is also a multiple of the smaller number.

The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. There are several methods for finding the least common multiple of two or more numbers.
Sometimes you need to write a radical expression using a fractional exponent. Example 2 Write 4 y6 using a fractional exponent. The answer is y3/2. Rewrite as a fractional exponent. Simplify. Sometimes there will be many variables in the radicand. Simplify each variable one at a time, then multiply. Example 3 Simplify 3 8x5y6z11 . 3 x2z2 .
