The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 665.
The divisibility rule for 665 is a method by which we can find out if a number is divisible by 665 or not without using the division method.
Check whether 1995 is divisible by 665 with the divisibility rule.
Step 1: Ensure the number is divisible by both 5 and 133, as 665 = 5 × 133. First, check divisibility by 5. Since 1995 ends in 5, it is divisible by 5.
Step 2: Now, check for divisibility by 133. Divide the number excluding the last digit by 133. Here, divide 199 by 133. Since 199 is greater than 133, subtract 133 from 199 to check if it's divisible by 133. 199 - 133 = 66.
Step 3: Since 66 is not divisible by 133, 1995 is not divisible by 665.
Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 665.
The divisibility rule of 665 helps us quickly check if a given number is divisible by 665, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
