Divisibility Rule of 628
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 628
What is the Divisibility Rule of 628?
The divisibility rule for 628 is a method by which we can find out if a number is divisible by 628 or not without using the division method. Check whether 1256 is divisible by 628 with the divisibility rule.
Step 1: Check if the number is divisible by 2, 4, and 157 (factors of 628). First, check divisibility by 2. The number 1256 ends in 6, so it is divisible by 2.
Step 2: Check divisibility by 4. The last two digits of 1256 are 56, which is divisible by 4.
Step 3: Check divisibility by 157. Divide 1256 by 157. Since 1256 ÷ 157 is an integer (8), it is divisible by 157.
Since 1256 is divisible by 2, 4, and 157, it is divisible by 628.
Tips and Tricks for Divisibility Rule of 628
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 628.
Know the factors of 628:
Memorize that 628 = 2 × 2 × 157 to quickly check divisibility by each factor.
Use divisibility rules for smaller factors:
Start by checking divisibility by 2 and 4, which have simple rules.
Repeat the process for large numbers:
Students should keep repeating the divisibility process for each factor until they confirm divisibility by all.
Use the division method to verify:
Students can use the division method to verify and cross-check their results. This will help them verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 628
The divisibility rule of 628 helps us quickly check if a given number is divisible by 628, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking all factors.
Students should check divisibility by 2, 4, and 157 to confirm divisibility by 628.
Divisibility Rule of 628 Examples
Problem 1
Is 12,560 divisible by 628?
No, 12,560 is not divisible by 628.
Explanation
To check if 12,560 is divisible by 628, use the rules for divisibility by 628.
1) Check divisibility by 2: The last digit, 0, is even.
2) Check divisibility by 4: The last two digits, 60, form a number divisible by 4.
3) Check divisibility by 157: Sum the digits (1 + 2 + 5 + 6 + 0 = 14), then check divisibility by 157 (not divisible).
Therefore, 12,560 is not divisible by 628.
Problem 2
Check the divisibility rule of 628 for 6,280.
Yes, 6,280 is divisible by 628.
Explanation
To check if 6,280 is divisible by 628:
1) Check divisibility by 2: The last digit, 0, is even.
2) Check divisibility by 4: The last two digits, 80, are divisible by 4.
3) Check divisibility by 157: Sum the digits (6 + 2 + 8 + 0 = 16). Since 16 is not divisible by 157 directly, and the number 6,280 is already known to be a multiple of 628, proceed to full division for confirmation.
6,280 ÷ 628 = 10, confirming divisibility.
Problem 3
Is 628 divisible by 628?
Yes, 628 is divisible by 628
Explanation
A number is always divisible by itself.
1) Check divisibility by 2: The last digit, 8, is even.
2) Check divisibility by 4: The last two digits, 28, are divisible by 4.
3) Check divisibility by 157: Sum the digits (6 + 2 + 8 = 16), then check divisibility by 157 (not divisible, but irrelevant).
628 ÷ 628 = 1, confirming divisibility.
Problem 4
Can 1,256 be divisible by 628 following the divisibility rule?
Yes, 1,256 is divisible by 628.
Explanation
To check if 1,256 is divisible by 628:
1) Check divisibility by 2: The last digit, 6, is even.
2) Check divisibility by 4: The last two digits, 56, are divisible by 4.
3) Check divisibility by 157: Sum the digits (1 + 2 + 5 + 6 = 14), then check divisibility by 157 (not divisible, but irrelevant here).
1,256 ÷ 628 = 2, confirming divisibility.
Problem 5
Check the divisibility rule of 628 for 18,084.
No, 18,084 is not divisible by 628.
Explanation
To check if 18,084 is divisible by 628:
1) Check divisibility by 2: The last digit, 4, is even.
2) Check divisibility by 4: The last two digits, 84, are divisible by 4.
3) Check divisibility by 157: Sum the digits (1 + 8 + 0 + 8 + 4 = 21), then check divisibility by 157 (not divisible).
Since 18,084 cannot be evenly divided by 628, it is not divisible by 628.
