The divisibility rule is a quick way to determine whether a number is divisible by another number without performing the actual division. In practical situations, divisibility rules help in doing quick calculations, distributing things evenly, and organizing items efficiently. In this topic, we will explore the divisibility rule of 496.
The divisibility rule for 496 is a method by which we can find out if a number is divisible by 496 without using traditional division. Let's check if 992 is divisible by 496 using this rule.
Step 1: Since 496 is a composite number, first check divisibility by its prime factors, which are 2, 2, 2, 31 (since 496 = 2^4 × 31).
Step 2: Check for divisibility by 16 (2^4). The last four digits of the number (0992) should be divisible by 16. 992 ÷ 16 = 62, which is a whole number.
Step 3: Check for divisibility by 31. Use the divisibility rule for 31: Multiply the last digit by 3, add the result to the rest of the number, and check if the sum is a multiple of 31. For 992, multiply the last digit (2) by 3, giving 6, and add this to the rest of the number (99), resulting in 105. 105 ÷ 31 is not a whole number, so 992 is not divisible by 31.
Since 992 is not divisible by 31, it is not divisible by 496 either.
Understanding and mastering the divisibility rules can significantly aid in mathematical calculations. Here are some tips and tricks for the divisibility rule of 496:
