Divisibility Rule of 756
The divisibility rule is a way to determine whether a number is divisible by another number without performing actual division. In real life, divisibility rules are useful for quick calculations, evenly distributing items, and sorting. In this topic, we will learn about the divisibility rule of 756.
What is the Divisibility Rule of 756?
The divisibility rule for 756 helps us determine if a number is divisible by 756 without performing division. Let's check whether 1512 is divisible by 756 using this rule.
Step 1: Check the divisibility of the number by 2, 3, and 7, the prime factors of 756. If a number is divisible by all these prime factors, it is divisible by 756.
For divisibility by 2: The last digit of 1512 is 2, which is even. Thus, 1512 is divisible by 2.
For divisibility by 3: Add the digits of 1512 (1 + 5 + 1 + 2 = 9). Since 9 is divisible by 3, 1512 is divisible by 3.
For divisibility by 7: Double the last digit and subtract it from the rest of the number. Here, double the last digit (2 × 2 = 4) and subtract from 151 (151 - 4 = 147). Since 147 is divisible by 7, 1512 is divisible by 7.
Step 2: Since 1512 is divisible by 2, 3, and 7, it is divisible by 756.
