Here's an easy trick to see if a number can be divided evenly by 4:
Check the Last Two Digits!
- If the last two digits of the number can be divided evenly by 4, then the whole number can be divided evenly by 4.
- If the last two digits are '00', then the whole number can be divided evenly by 4.
Let's look at some examples:
-
Example 1: Is 316 divisible by 4?
- Look at the last two digits: 16.
- Can you divide 16 by 4 evenly? Yes! (16 ÷ 4 = 4)
- So, 316 is divisible by 4.
-
Example 2: Is 524 divisible by 4?
- Look at the last two digits: 24.
- Can you divide 24 by 4 evenly? Yes! (24 ÷ 4 = 6)
- So, 524 is divisible by 4.
-
Example 3: Is 700 divisible by 4?
- Look at the last two digits: 00.
- Since the last two digits are '00', 700 is divisible by 4.
-
Example 4: Is 123 divisible by 4?
- Look at the last two digits: 23.
- Can you divide 23 by 4 evenly? No! (23 ÷ 4 = 5 with a remainder)
- So, 123 is not divisible by 4.
In summary: Just focus on the last two digits of the number. If those two digits can be divided evenly by 4 (or if they are '00'), the whole number can be divided evenly by 4!
