I hope the video for this skill helps. Students will not only need to know factors and multiples, but they will also need to know how to find the Greatest Common Factor (GCF) and Least Common Multiple (LCM) for a given set of numbers. There are practice problems, word problems, and an answer key below.

multiplication and division work should be done by means of practical tasks involving children themselves, ‘real’ objects or mathematical apparatus in which the context is entirely apparent. Similarly, recording of multiplication and division work should also, for the most part, contain some representation of the operations attempted.

The squares 2 2 = 4 and 5 2 = 25 are factors of 100, so every multiple of 100 is a multiple of 4 and of 25. Thus to test for divisibility by 4 and 25, we only need to look at the last two digits. Thus to test for divisibility by 4 and 25, we only need to look at the last two digits.

This is where the concept of divisibility rules comes into play. The process of whether the given number is exactly divisible by another number without actually performing the operation of division is called the test of divisibility. Being exactly divisible means that on division there is no remainder left.

To solve this problem, the first thing we have to do is break down both numbers into prime factors. 24 = 2 3 x 3. 18 = 2 x 3 2. Now, to calculate the GCF, we need to choose the common factors with the smallest exponent, which in this case will be the 2 and the 3. Once we’ve chosen our common factors, all we have to do is multiply them by each ...
