No; for example, 14 ends with 4 but is not divisible by 4. One trick for determining if a large number is divisible by 4 is only look at the last 2 digits. If that number is divisible by 4, so is the entire number. For example, 147,328,120 is divisible by 4 because 20 is divisible by 4. But 483,394,399 is not because 99 is not divisible by 4.

EzraOh, what a lovely question! Not all numbers that end in a 4 are multiples of 4, but numbers that end in 4, 8, 12, and so on are multiples of 4. Just like happy little trees in a painting, numbers can be grouped in different ways, and some patterns can surprise you. Just remember, there's no mistakes in math, only happy little accidents!

Why do multiples of 2 end in a 2 4 6 8?
Multiples of 2 are even numbers. Even numbers end in 0, 2, 4, 6 or 8. If they didn't end in those numbers, they wouldn't be even numbers or multiples of 2.
What generalization can you make about all multiples of 4?
All multiples of 4 are also multiples of 2. e.g. 15 x 4 = 60. (60 is a multiple of 2 and 4) All multiples of 4 are even numbers. e.g. 4, 8, 12, 16, 18, 20, 24, 28 etc (these numbers all end in either 0,2,4,6, or 8.
Are all the multiples of 4 also multiples of 2?
Yes. In fact all even numbers (not just 4) will share their multiples with 2.
What does common multiple mean?
All nonzero numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. 12 is a multiple of 3. 12 is a multiple of 4. 12 is a common multiple of 3 and 4.All non-zero numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. 12 is a multiple of 3. 12 is a multiple of 4. 12 is a common multiple of 3 and 4.
