How Do You Know If 36 Is Divisible by a Number?
A number is divisible by another number when the division produces a whole number with a remainder of zero.
For example:
36 ÷ 4 = 9
Because the remainder is 0, 36 is divisible by 4.
Now consider:
36 ÷ 5 = 7.2
This does not produce a whole number, so 36 is not divisible by 5.
Is 36 Divisible by 2?
Yes.
36 is an even number because its last digit is 6. Every even number is divisible by 2.
36 ÷ 2 = 18
Therefore, 36 is divisible by 2.
Is 36 Divisible by 3?
Yes.
To check divisibility by 3, add the digits:
3 + 6 = 9
Since 9 is divisible by 3, 36 is also divisible by 3.
36 ÷ 3 = 12
Is 36 Divisible by 4?
Yes.
The last two digits of 36 are 36. Since 36 can be divided by 4 evenly:
36 ÷ 4 = 9
Therefore, 36 is divisible by 4.
Is 36 Divisible by 5?
No.
A whole number is divisible by 5 when it ends in 0 or 5.
Since 36 ends in 6, it is not divisible by 5.
36 ÷ 5 = 7.2
Is 36 Divisible by 6?
Yes.
A number is divisible by 6 when it is divisible by both 2 and 3. We already know that 36 is divisible by both.
Therefore:
36 ÷ 6 = 6
So, 36 is divisible by 6.
Is 36 Divisible by 9?
Yes.
Using the divisibility rule for 9:
3 + 6 = 9
Because 9 is divisible by 9:
36 ÷ 9 = 4
Therefore, 36 is divisible by 9.
Divisibility Rules for 36
There is a useful way to check whether a number is divisible by 36.
Since:
36 = 4 × 9
a number must be divisible by both 4 and 9 to be divisible by 36.
For 36 itself:
- The last two digits, 36, are divisible by 4.
- The digit sum, 3 + 6 = 9, is divisible by 9.
Therefore, 36 is divisible by 36.
