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 640.
The divisibility rule for 640 is a method by which we can find out if a number is divisible by 640 or not without using the division method. Check whether 7680 is divisible by 640 with the divisibility rule.
Step 1: Check if the number is divisible by 10. The number 7680 ends with 0, so it is divisible by 10.
Step 2: Check if the number obtained by removing the last three digits is divisible by 64. Here, the number is 7 (since 7680 becomes 7 when we remove the last three digits, 680).
Step 3: 7 is less than 64 and not divisible by 64, so 7680 is not divisible by 640.
