Divisibility Rule of 198
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 198.
What is the Divisibility Rule of 198?
The divisibility rule for 198 is a method by which we can determine if a number is divisible by 198 without using the division method. Check whether 396 is divisible by 198 with the divisibility rule.
Step 1: Since 198 is the product of 2, 3, and 11, check the divisibility by these numbers.
Step 2: Ensure the number is even to check for divisibility by 2. Here, 396 is even, so it passes this test.
Step 3: Sum the digits of 396 (3 + 9 + 6 = 18) and check divisibility by 3. Since 18 is divisible by 3, 396 passes this test.
Step 4: To check divisibility by 11, alternate sum the digits: (3 - 9 + 6 = 0). Since 0 is divisible by 11, 396 passes this test.
Step 5: Since 396 is divisible by 2, 3, and 11, it is also divisible by 198.
