What is the greatest common factor of 1218 and 42?
First, using your 2 divisibility rule, we find that both are even, therefore both are divisible by 2. Now, using the 3 divisibility rule, we know that 1 + 2 + 8 + 1 = 12, and 4 + 2 = 6, both multiples of 3. Thus, it must be divisible by 3 and 2, and it must divisible by 6! If so, then dividing both by 6 yields:1218/6 = 203, 42/6 = 7.Now both values are prime, therefore, 6 is the GCF of 1218 and 42.

How can you tell that 42 is divisible by 3?
Well, honey, you add up the digits of 42 (which gives you 4+2=6) and if that sum is divisible by 3, then the original number is also divisible by 3. In this case, 6 is divisible by 3, so yes, 42 is divisible by 3. Math can be fun when you know the tricks!
