Divisibility Rule of 188

The divisibility rule for 188 is a method by which we can find out if a number is divisible by 188 or not without using the division method. Check whether 5644 is divisible by 188 with the divisibility rule.

Step 1: Identify if the number is divisible by both 4 and 47 (since 188 = 4 × 47). First, check divisibility by 4: a number is divisible by 4 if the last two digits form a number that is divisible by 4. In 5644, the last two digits are 44, which is divisible by 4.

Step 2: Now check divisibility by 47: There is no straightforward rule for 47, so perform a quick division if necessary to verify.

Step 3: Since 5644 is divisible by both 4 and 47, it is divisible by 188.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 188.

• Know the multiples of 188: Memorize the multiples of 188 (188, 376, 564, etc.) to quickly check divisibility. If a number matches one of these, it is divisible by 188.

• Check divisibility by 4 first: If the last two digits of the number form a number divisible by 4, proceed to the next step.

• Use the division method for divisibility by 47: Since 47 has no easy rule, perform division to verify.

• Repeat the checks for large numbers: For large numbers, ensure both conditions (divisibility by 4 and 47) are met.

• Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.

• Divisibility rule: The set of rules used to determine whether a number is divisible by another number without performing full division.

• Multiples: Numbers obtained by multiplying a given number by an integer. For example, multiples of 188 are 188, 376, 564, etc.

• Integer: A whole number that can be positive, negative, or zero.

• Division: The process of determining how many times one number is contained within another.

• Subtraction: The mathematical process of taking one quantity away from another.
